Here is the problem:
- Steemit.com is run by Steemit Inc
- Steemit Inc is incorporated in the USA.
- Because of this Steemit.com (and it's users) would need to comply with AML & KYC regulations.
Steemit Inc very early on stated that they did not want to be labeled a money transmitter by the US authorities.
This doable but it has to be done outside of Steemit.com
I agree. Steemit Inc themselves would not want to directly exchange steem for dollars. But we are completely free to do it among ourselves.
