I agree with this up to a point. I think there should be little that limits people from being able to invest as much as they want but then you have to consider the same limitations with IRAs and 401Ks. Not saying investing in a new startup is just like investing in an IRA or 401K but I can certainly understand it from that perspective. Maybe the answer isn't limiting the amount that can be invested but increasing oversight on the companies people are investing in. No one wants to be taken for a ride even though the risk is above average in this case.
