What kind of quote is that? Markets are clearly many-to-many by definition. Money doesn't even have a meaning or value without markets. It's just paper without markets.
I think the idea is that "more capable" participants tend to make money off of "less capable" participants. And there are a lot more of the "less capable" ones.
Markets are like ecosystems, they are an emergent property of the aggregated activity of many participants. Yes, some of those participants will end up at the top of the food chain. But that's going to happen regardless of what you do.
Not sure if you're arguing against Ethereum, cryptocurrencies as a whole, or capitalism as a whole? Your point would be better understood if you explained what you mean a bit more.
Unregulated capitalism. Regulation limits how much information/expertise disparity can tip the scales. It doesn't prevent it altogether (nor is that a constructive objective), but limits it so the distribution between the winners and losers ensures still reasonable outcomes for the loser.
All that's happening in crypto is the same exploitative games/vehicles that happened in other markets before regulation protected the least informed and least Machiavellian players from the worst outcomes. There's no real innovation in that respect.
It is in the nature of markets to move money from the many to the few.
