It does not make sense to take control away from people who are running companies and have all their assets tied up in them like Zuckerberg, Bezos, et. al. This is a disasterous recipe for sure. But once they are not longer doing that or especially when they die it's easy enough to tax it then. And yes it would wipe up some venture capital, but that's already going gangbusters. It went from 25 billion to 90 billion in 10 years, 4x growth. So yes it would reduce some of that.
