What many people don't realize is that the operational and customer service costs of payments don't scale with payment amount. Customers will cost almost just as frequently dispute, have questions, have problems, ask for help, attempt to defraud etc with a $1 transaction as they will a $100 or $1000 transaction. This is the real killer with micro payment schemes. Customer service costs scale more with number of payments than payment volume. And these real costs are born by Patreon, by the networks and by the banks which is why min txn costs exist. The crypto bros totally miss the point in understanding this too.
