Yes, it's too bad about the fiat system, but we're hoping to replace it, or at least provide an alternative....

Lets add a centralizing feature/flaw to a system that is built to be decentralized. Hmmmm....what could go wrong?

Maybe we could further exasperate the issue by layering privacy onto those nodes and sell it as a fee for services (shhhh, or some coin will mistakenly think this is a good idea and dupe users/noobs into paying for their developer's/shill's caviar dreams).

Sorry, been arguing with d'tards dashers all day. Without being able to validate trustlessly that the nodes aren't owned by one person or one too few, you are forcing an extra layer of centralization onto the coin--the nodes will act as an XMR aggregate that will continually churn coins to those have the most nodes, who buy more nodes to get more fees to buy more nodes to collect fees and so on and so forth. There's enough issues with how do you keep mining decentralized, so adding another problem to solve seems counterproductive.
