Anyone noticed that we have breached 17,800,000 BTC already? Which means that 85% of all BTC have been mined. And in the next 10+ years we can all assumed that 'almost' all bitcoin is mined already.
This is why I'm a small blocker. The inflation subsidy is quickly dwindling down. In just a few more halvings, it will hopefully be negligible compared to transaction fee revenue -- otherwise we might need to start worrying about major drops in hash rate, reorganization attacks, etc. Any increase to block size will lower fee revenues, so I'm definitely on the conservative side when considering them.
