So, do you mean that the less wealthy people don't go for rent-seeking etc?
That's just bollocks. The system rewards innovation, not just that consistently and probably not that much. And people in all income classes behave the same way.
Token is like a bearer share which can be transfered digitally from person to person. Bearer shares are not that common nowadays but I understand that in the past they were quite popular.
Not in that sense. But one open sourcing I was witnessing revealed other sensitive information (credentials), and resulted in a huge losses to the company.
What is seen as fair is a very subjective question. I would prefer not calling it "fair share" because taxation is very complex and depends hugely on how good you are at gaming the system.
Because those who have the power will always tax those who haven't, for the simple reason that it is much easier than gainint the money via voluntary exchange.
