At the end of the day, Tok, it requires the greater-fool to pay a taxation
Well I am not an "oligarchical pot holder" as you call it. I bought mine on an exchange - and quite late in the day I might add.
All the same, I'm not paying taxation to anyone. My wallet balances go up not down. Anyone with any amount of holding can avail themselves of the same benefit.
Everyone's of course free to interprate different network policies and systems how they like - if you want to paint it as 'taxation for pot holders' be my guest. I interpret it as balancing the interests of all stakeholders - miners, holders, commercial users and maintainers. Without that balance you can mine all the tax free tokens you like if you're happy for them to end up worthless.
As for "centralisation", and "nodes" it's fairly academic.
One of = centralised
Many of = decentralised
One of many owned by an oligarch = a taxation for centralized services that puts an infinitely increasing amount of profits into masternode holder's hands for doing nothing but sitting on their butts and hyping new-users/the-naïve/greater-fools with empty promises of decentralization and moon landings.
