It's not solely an issue of greedy server owners. I like pay to win because as an adult with a job when I want to build a massive fortress I don't have the time to devote to mining all the stuff necessary. I much prefer donating $20 or so for in game currency then buying the materials I need at the server's shop. A castle I built recently used 27,641 stone bricks. Having to obtain them manually would take quite a lot of time.
