When you say "disowning individuals" can I assume you're referring to something like setting very high rates for inheritance tax? Why do you think high inheritance tax 'historically does not tend to work well for innovation'?
I should clarify, I think there are a lot of good reasons for high inheritance taxes if reasonably structured. I meant disowning people who are still alive in a communist sense (do not want to start a discussion on socialism/communism though), i.e. the government literally deciding someone is not fit to own such a big piece of the means of production and taking it from them.
