I understand I agree it's expensive and impractical for micro trades its just I get the logic behind it, going to zero means no incentive to protect the network, security trumps all and that comes at a price.
Anything else is by definition less secure, cheaper doesn't always mean better, it means trade-offs. Will ETH and BTC become cheaper to use with time? Yes, but there is a limit because they need to strike a balance between incentives and security and support for decentralising the network.
I think wrapped layer 2 solutions will be what we use in future where we settle on side chains instead of on-chain. For now, we stuck with the growing pains
