But to sell the calls, you should own the stock first. Puts can be bought w/o owning the stock. Granted, the put buyer pays the premium, so you don’t get guaranteed money in your pocket like you would selling calls.

I think you're referring to covered calls, but you can sell naked calls as well, meaning without owning the underlying.

That's actually not a concern I'd have, because hardware that has been sufficiently tested and burned in tends not to fail for a very long time. I've done builds that ran for 5+ years with virtually no physical attention, just continual degradation as hardware is taken out of service. There's also not much money to recover from 5+ year-old hardware. I used to run AI inference GPU servers in road vehicles, which is pr…

uhh no I dont think the road vehicle is harsher than a rocket launch

5 years is a Starlink's typical lifetime. Data center satellite lifetimes will probably be shorter. Demise sooner, replace more often. GPUs get more energy efficient every year and leaving the slower, hungrier chips up there much longer than 3 years seems wasteful given the cheap cost of launch. I think this could be done at an interesting scale even on Falcon 9 alone. If Starship does even 20% of its early design go…

SpaceX has accomplished spectacular things in reusable launch vehicles and space-based networking. It will soon restore the heavy launch capability that the US lost when it retired the Saturn V in the 1970s, but in an affordable and sustainable manner. SpaceX is almost single-handedly keeping the US ahead in space. I'm bullish on SpaceX as a company in terms of technical accomplishment. Buying SPCX would make sense a…

Yes but... All the "value" in SpaceX is in AI. Actual space launches are a tiny part of the portfolio. Talking about launch capability is almost off topic when taking about SpaceX valuation.

I completely understood the idea of Starlink and expected that it would be successful and useful, which it is. I've worked in data centers for decades now, and I am incredibly skeptical of the "data centers in space" sales pitch. It seems like an actual scam. Data centers submerged in the ocean or placed in the desert seem much more promising. But I have only an enthusiast's understanding of rockets and physics, so I…
