To play devil's advocate: you may not need VC's as much in a UBI world. You don't have to worry about income if your startup fails, so you're less likely to play the VC lottery in hopes that you can ride the funding into a successful exit.
Exactly. In a UBI world, the government becomes the investor for innovation. If an idea you tried doesn't work out, you try something else. It becomes much easier to start a business, and you no longer get kicked out on the street for failing.
