They aren't using any tax dollars for Starship. It's entirely funded by their profits (at least as far as I know). And this Starship MK1 is/was a prototype designed to test some aspects of their design in the real world. It was never going to be anywhere close to taking people onboard. Even this incident had all people far away before they started doing anything like pressurising. This is active development, every single rocket company or program in existence has had explosions and test failures, and they will continue to have them. The important part is that they are doing this safely and nobody is getting hurt, these are controlled tests. It may not be the way you think rockets should be designed and built (I'm personally kinda skeptical that they will actually build the full prototypes/rockets outside like this), but it's not more dangerous than any other rocket company.
