if you're really able to believe such a ridiculous idea than what use is proof of work at all?
Oh noooo .01% of my stack goes in a trusted ECash mint that offers instant asynchronous fully anon payments boooo. Worry about your own money

people are suggesting for DNMs with millions in volume to do their business inside ruggabe ecash mints, and that ecash mints will eclipse monero completely. please stop pretending this advocacy is confined to pocket change. and we both know the whole point of L2 scaling is to inherit security from L1 and execute transactions somewhere else. you toss the security from L1 into the garbage bin the moment you put one toe into an ecash mint. the developers are retarded and need to go back and come up with something better.
