Even if it started with an equal distribution, the shares would quickly accumulate because the poorer shareholders would be lured to sell in prices that thought were "OK". They'd be trading what -to them- are useless tokens worthless for their day to day survival, with btc->$$$ which have tangible RL impact.
The difference is the power-law distribution would be derived from competition. So you would have a wider diversity of whales not just the insiders. The power-law distribution doesn't give 50% to the upper 0.1%. Rather it is 38% to the upper 1% (c.f. the references
I cited earlier today upthread).
Also I think we can keep the n00bs accounts locked up 104 week withdrawals, so the power-law can't force liquidation so rapidly. Giving the n00bs a chance to partake of the upside appreciation. The power-law distribution will still form amongst the content creators earnings as well, but again in a competitive environment.
