Some users may prefer the convenience of a regulated online exchange. If it gets them into Bitcoin, while giving them a feeling confidence and security, that would be beneficial.
Many of us prefer to use other methods that do not require sharing personal financial information.
This is the internet. No one has a monopoly.
I don't mind a responsible base of regulation. I'm not full on "anti regulation." But it shouldn't be worse than the banks and paypal and that's what both coinbase and circle. As mentioned, paypal didn't require a license or scans of crap or a selfie. My bank did use the license but I get that. I really truly hope there are serious devs out there who are able to come up with a legitimate means of decentralization and no need for regulation.
