Well, you can make things yourself worth 365 x 100 million and decide to use them for something else.
Fortunately, the rules in well-functioning societies do not allow anyone other than the owner of something to decide how it should be used.
If you spend your own money sure why not, I couldn't agree more, but it's the taxpayer's.
This very same individual was until recently trying to highlight frivolous government spending, surprisingly coming up short, obviously it'd be very cynical of me to suggest even a hint of hypocrisy let alone a conflict of interest so I'll leave it.
SpaceX is not financed by taxpayer money and I believe its contracts are paid on reached milestones.
Musk said it himself "that's $100mm every time but it's the taxpayer footing the bill and they should get value for money" (paraphrasing), I can't remember the show but it may have been his Rogan appearance.
Sorry to burst your bubble on that, even if it is just carrying Starlink satellites it's still at public expense, not limited to the rocket itself but the infrastructure, and oversight from third parties.
I have to ask if the world needs 365 $100mm fireworks each year.
