Even more so because realistically you need to set it up somewhere where electricity is cheap which which is a centralizing force in itself. Also you need to have a really efficient mining rig for it to be profitable. With Ethereum PoS you can easily home stake on a Raspberry Pi which means it is much easier for regular people to participate.

Oh yeah for sure. Not at all denying that. PoS is just more on-the-nose about it.
