Okay, now you want to put more satellites in the sky, for weather and gps. Is there some evidence that what we have now is not enough or wouldn’t ever be replaced? I cannot find anything online about that. So I still do not see how this will necessarily improve my daily life as the weather information I have now is already good.
There are 3 new GPS satellites being launched by the US in 2025. Satellites do regularly need to be replaced; fuel runs out, batteries die or there os damage or failure. We also are developing newer and better satellites.
Satellite based internet is currently going through a revolution that is bringing internet access and economic opportunity to isolated small communities all over the world. This is a great example of new deployment that simply wasn't economically feasible with pre-SpaceX launch prices. This technology has so many potential positive impacts that it alone should justify reusable rockets. This is another application that could save the life of someone you love (better acess to emergency services in remote locations or deadzones).
Another incredibly valuable satellite industry is satelite based imaging. Timely, high precision satellite imagery is currently very expensive. Significant drops in the price would enable a unimaginable plethora of usec ases. Better wildfire monitoring, more efficient farming and ranching, search and rescue, etc.
On top of all this, starship development is actually comparatively cheap compared to how valuable space is. Losing GPS would cost the US alone 1 billion dollars a day which is why the US is planning on spending 2 billion building a backup. Starship RnD costs are estimated to somewhere near 10 billion total spread out over a decade or two.
For further comparison, I'll also note that the 2024 US presidential election cost us more 50% more than that. The entire space industry is worth about as much as the entire semiconductors industry (~600 billion) and McKinsie estimated that to triple in the next 10 years.
Finally, I'll say that what I've listed is the merest drop in the bucket compared to the uses we haven't figured out yet because space launch was so expensive.
An second order of magnitude drop in launch costs on top of the ond SpaceX has already delivered would be a big boost the the global economy in many ways, including some that are hard to predict on advance. If SpaceX can deliver a third order of magnitude drop beyond that (which has been claimed as possible with Starship) then the results would be staggering, completely transforming how we view and use space economically and enabling completely new types of space exploration missions.
The biggest problem right now is that nobody else is keeping up with SpaceX. We need more companies doing the same thing SpaceX is.
