Monero can support roughly 100x more transactions on current protocol with no more upgrades without straining current tech limits. It already cut down transaction size by ~80% since inception. It's scalability will keep improving over time and consumer tech is always getting better.

Monero is for anyone, not necessarily everyone. If you think the masses are going to want to live in a state of cryptoanarchy I think it sounds pretty copium... But anyone that wants is free to use Monero it is open and permissionless.
