We are going in the right direction!
This is bullshit though because you have no way of knowing if the same person owns multiple pools or not, or if a cartel of different actors all colludes together even if they aren't the same people. Just like the current banking system for instance. People that have studied the topography of the traditional banking network claim there's not multiple banks but just a "one bank". So the traditional banking system already does this obfuscation, which designed to centralize bitcoin will inevitably do as well.
This is one reason bitcoin DOES NOT solve the Byzantine generals problem. You can theoretically have 10 different shell pools all owned by one guy or cartel and be under 51% attack 24/7 with nobody able to verify if it's true or not. The burden of proof isn't for others to prove bitcoin is centralized, it's for bitcoin to be able to prove it's not, but it has no possible way to do so. Just the act of double spends not occurring proves nothing. It can still be a monopoly the entire time. Centralized transaction validators having the ability to blacklist transactions (permissioned ledger) is just as big of a problem as double spends anyway.
