Isn't it literally the government's job to legalize theft and pick the winners and losers? One of the government's main tools in regulating the outcomes of a country is tax policy and if you want to call that theft, sure, go ahead. It doesn't make it the wrong course of action to take. You even lay out a remarkably cohesive argument for that 'theft' in your statement: if wealth provides an excess of agency for the wealthy, the only way to optimize for maximal opportunity (or maximal innovation if you'd prefer that framing) is to reallocate opportunity capital from the hyper-rich to the general population. The way you get more entrepreneurialism is not by increasing the payout for 'winning' the startup lottery, it's by letting more people play.
