I've been thinking about network scalability and transaction fees when it comes to blockchain networks and I think this might be a feature and not a bug. If Ethereum is too expensive it seems like it would be relatively easy for 100 people to create a network of 100 nodes and start a new network. The transaction fees would be negligible and if each node had an api also you could support a bunch of clients.

as long as creating, discovering etc. becomes relatively easy. good buy network effects.

Ethereum has a long term scaling plan with L2 and sharding

Then your back to some organization controlling it.
