Any stage in making a mars trip viable is a multi-billion dollar project. Actually arriving on or around mars has no value in itself other than the achievement and some science, but the runup will possibly make SpaceX the wealthiest company in the world. Or at least pull tens, hundreds of billions out of the US economy.
And most of NASA's budget is not spent doing stuff, but on thinly veiled graft like the SLS which obviously will not be redirected to SpaceX because the goal isn't to achieve anything, but to spend money on interests tied to the people directing the spending.
From Musk's perspective, NASA is an unnecessary, inconvenient middleman. Eliminate the public middleman, and everything goes to private companies, in other words, to SpaceX. And it's not just about NASA; the current administration wants to privatize the entire government, including the US Postal Service, for example.

Musk/DOGE currently controls all federal spending.
