Okay so startup capital aside, you like PoW because there's an ongoing cost to participating in consensus and don't like how PoS is more or less free.

I'm not sure how you arrived at this when your initial complaint was the rich get richer with PoS. PoW has much higher costs to participate and after a few years you have more costs when you need to upgrade your mining rigs because they're either burnt out or outcompeted by newer hardware.
