And people stay productive by enjoying hobbies and playing games. It’s an investment in infrastructure, just like fire, healthcare, police, power, water, transportation, etc.

You can enjoy hobbies without paying for unfinished games, early access is completely besides the point here. You can buy games when those are ready and be equally productive. If you like early access games you’re free to buy them, I have nothing against it. But it’s not an ‘investment’. It just a discount.
