While I don’t think the "Space Force” is a bad idea per se, especially for the long term, I do highly doubt that the Orange Smurf and Teddy here actually really thought it through. I mean, for starters no human power is a threat to our spacecraft, while any Alien power would be waaaaaaay to much out of our league at this point.
No, more likely the Orange Clow just had another highly impulsive idea (thinking that with enough money he can build his own Galactic Empire and Death Star) while Cruz here is just brownnosing his Emperor for a taste of that UNLIMITED POWER.
But you know what? The first world nation and human leader that successfully gets our very own Star Destroyer (*) build will have my support no matter what.
(*) The Resurgent-class happens to be my favorite, btw.
