That seems like something we would want, the ability to freely transfer payment from one individual to another, internationally, contractually, and transparently.
The only interests that I would think would want that gone are those that profit from the many choke points in our financial systems. Sure, speculators and opportunists have leveraged benefits, and they are the ones you always hear about… you don’t hear about the millions of people quietly managing their private and legal financial affairs, because when you use it for that, it just works -exactly as designed.
FWIW I think you can much more easily associate cash with all kinds of shady and socially caustic uses, but for whatever reason not very many cryptocurrency critics are out to abolish cash, which I would think would be the poster child for seedy, shady, toxic commerce.
But, sure, crypto bad and whatever.
