Getting them listed on regular exchanges might be tricky due to the whole "security" deal, I guess. As the SEC pointed out, the original DAO was most likely in violation of U.S. security law.
And while the U.S. is not the end-all, be-all of blockchain and token economy, there is still a chance that other countries may follow suit and adapt the U.S. view. I really wonder how that might pan out.
The US law is not new and don't think most of the countries find it favourable. That's y it has been adopted else where. More so, some of this don't really look like it is. It does not actually stop but restrict, they are also meant for ICO safety. Some ICOs still serve the US ecosystem.
