Agreed! That's why I'm continuously advocating practical articulations between some cryptocurrencies and the to date most widespread "altcoins", i.e. the 5,000+ local alternative monetary units (like the famous "Bristol pound", in the U.K.). State authorities can enforce a ban on any blockchain-based money they're hostile to, but it'd be way harder if they have to deal with currencies based on REAL communitary solidarities (between neighbours, coworkers, church members, etc.).
