It's almost as if some people aren't aware you can buy a game in Early Access at a lower price, to support the developer during the game's development when funds are needed most, and then not play it until full release.
It is, indeed, possible to buy a game now then wait a few months or years before you play it.
Same with people asking "When does this come out?"
It is out. It's not finished yet, but it's out - you can purchase it right now.
If you want to support the developer, and you intend to play it on release anyway, why not buy it right now? Why wait? Go ahead, give Vince your money.
