Deregulation
Regulation can exist for a couple of reasons. A big one is that there isn't enough information in a market, so customers could be abused -- you need regulation to ensure they're getting a fair deal.
But the internet has given us much more liquid markets with much more information. This protects customers by itself -- in a big and efficient enough market, they can easily figure out if they're getting a fair deal. The price signal itself may be sufficient.
There's a neat circle of life here: new markets need rules to create the trust that enables transactions. As the market matures, the rules can slowly be removed, with a truly efficient, at-scale market working automagically.
(This dynamic explains a lot of useless regulation you may run into -- the rules are often historical artifacts from a smaller-scale time.)
