Fraud is certainly a concern, and the reason that the laws were introduced in the 1930s in the first place. But the S.1791 bill has provisions for dealing with this through (relatively) strict individual investing limits and reputation via crowdfunding intermediaries. A balance needs to be struck between protecting "less sophisticated" investors and giving those of us who want the opportunity the chance to get involved, help support entrepreneurs, and create jobs (on main street and in silicon valley). There's still a lot to be hashed out of course, but this would be a step in the right direction.
