Regardless of whether or not we believe some of this stunt was CGI'd, we also have to see what we get out of funding this through our taxes. So...what do we get in return for paying for private companies like Elon's? Here's my take on it:
1- Inspiration for a future generation of innovators.
2- Belief in being able to reach the stars.
3- Ideas for entrepreneurs on how to use wacky advertising to cross-promote your products.
4- Ideas on how to sell your products with gigantic propaganda

While I would much rather keep my money, at least this company taking my tax money gives something (even if its fake) in return. Most of other companies that take government money don't give anything in return, but instead use the money taken from the government to further enslave us (i.e., Banks).

Anyway...as for me...I would rather keep my money and us it as I see fit.
