Sorry to pose a stupid question: what are the reasons why the limit cannot be raised?
main reasons that opponents to the increase state are:
- centralization
- fees discovery price distortion
- UTXOs size will increase significantly
- Tor could not be used anymore
- other things we don't know yet caused by rising block max size.
All valid reason to keep developing and not accept the 20MB block proposal as a final solution. To attempt solving those problems buy limiting block size is an expression of a lack of creativity
