Or if it's going to be an ICO then put in the infrastructure to allow for a fully legal crowd funding launch to take place via an SMT. Partially legal or push a button to possibly break the law only confuses the situation. Let each issuer determine their own jurisdiction and announce their jurisdiction to investors. Let issuers put forth terms of service agreements and other legal protection mechanisms which investors can click to sign. Let issuers choose which investors to include or exclude from their ICOs so as to reduce their level of risk exposure.
If an issuer in a country where it's legal to crowdfund is trying to avoid SEC problems then all they have to do is put up a legal defense and an exclusion notice telling US investors not to participate. Just exclude US, South Korean and Chinese investors to reduce your risk if you're doing an ICO.
