Just to be clear, these may incur some tiny costs, but if at network level we use one of these as native currency then it would be an exception and free

This is not a simplification for me This would mean creating a native transaction for creating a non-native transaction. Add to that additional code needed to differentiate between two types of txs…

What is the rationale behind making it paid?
