Not all web 3 application require payments(e.g. poap.xyz), especially with more cheaper L2 chains coming, it is more like a on-chain immutable proofs and data reusability.

If we make everything free of charge, who should pay all the awesome open source developers, how can they make a living? Micro-payments is at least one of the possible solutions.

I do admit lack of tools in current state of web3 world and it becomes money grabbing for some people

Inefficient distribution of fiat system might be the reason for someone can't afford to access web3. I think paying a little bit still better than being a product of all the adds company.

Also, without developers’ buy-in, web 3 WILL be nothing
