I'm a lot bigger than a bullet but it can still punch a hole through me.
and it won't affect your buoyancy at all.
When shot with a rocket all the air leaks out of the steel barge.
Am i missing something, is the need to land vertically a requirement of a fragile fuselage? Seems wasteful to carry extra anything (in this case rocket propellant) to space, just to avoid having to re-right the rocket when you get it back on earth for a subsequent launch. Is extra fuel payload < landing gear or parachutes?
Lack of wings. (That's obviously for the landing gear part of the question) But fragile fuselage is certainly spot on. Parachute-landings still have quite some impact velocity. Strengthening an object the size of a Falcon 9 first stage to survive that impact would require a much stronger and thus prohibitively heavy structure, even if the parachute itself was free. The nice thing about powered upright landing is that…

I don't see how chanting for a group, without any implicit or explicit diminishment of other groups compares to hate speech against sexual minorities. Also, chants are not a company policy, it's what employees spontaneously do in their own private space, which you saw on their own private broadcast. (If we're bringing SJW approach into this, then I think you're advocating the minority (SpaceX employees) should adapt…
I too find it hard to see how so many have conflated chanting for a group, in this case the USA, as being equivalent to actively admonishing another group. The employees at SpaceX aren't burning the flags of foreign countries or otherwise disrespecting or mocking them, they are simply expressing pride in the nation that many of us view as playing an instrumental part in our success. I also don't know what could be do…
I don't think is enough or appropriate. A significant fraction of global viewership is disturbed and alienated by the chants. It might well be that they're having the wrong feelings for wrong reasons, but realistically they will not adapt, and SpaceX's actions will not change their attitude in this regard, and they will continue to feel alienated.
I would like to see this properly weighted and considered as a consequence. It's similar to many other situations where you believe that people with different religions and attitudes are offended for ultimately wrong reasons, but you still don't go casually provoking them or making them feel bad.

This pool of freshwater would need to be many kilometers in diameter to give a high chance of hitting it with an unpowered parachute descent (thanks to unpredictability of the winds). At this point you are talking about doing something that is much, much more expensive than the current approach of a powered landing. How are you going to get so much freshwater out into the sea, anyway? That's way more water than could…
A freshwater lake would seem easier

Cargo shifting is a big deal. The yearly casualty rate for Bering Sea crab fishing used to be over 1% per year, because the shifting weight of crab pots on overloaded vessels in heavy seas. I saw a training film when I was aboard a tender boat in Alaska. Those boats could look fine one minute then capsize and be as good as sunk in the next 2. Shifting weight on vessels has and does cause rapid capsizing and deaths at…
This is pretty light cargo relative to the weight of the ship. It's a few tons of rocket and thousands of tons of ship. I don't think it's going to matter to the ship if it shifts, the only risk is losing the rocket over the side.

Completely incorrect. The question to ask is, why are they bothering to land at sea? And, if you had done any cursory research instead of just announcing that SpaceX is making a PR grab because it sounded good to you, you would have read in the abundantly available explanations that this launch was to geostationary transfer orbit, rather than low earth orbit. GEO is a lot, lot higher than LEO, which means the rocket…

I always try to watch the webcasts and I can't help but cringe so hard when they start chanting 'USA USA USA', every single time. What is up with that?
It's a quirky American thing. But plenty of other countries do it to. Not surprisingly it originates in sports like most of these kinds of chants. Go to an international football/soccer match sometime and let me know how many national chants you hear. https://www.youtube.com/watch?v=FwHFm3pBA90 ("TAE HAN MIN GUK!" "Great Korean People's Country") Here's a show giving fun lessons on how to properly do the chant https:…

Or not, because the next best alternative is much more expensive than SpaceX's current pricing. We're dealing with a corporation -- I'm not sure we can count of them to "pass on the savings".
We're dealing with a group of people with strong ideas about space. They probably won't pass on much of the savings, but for a different reason - they need the budget for Mars project. That's the whole purpose this company exists in the first place.

Other then subsadising your own industry and for military reasons, their is no argument for making your own rockets. Both those are terrible arguments.
