Notice I said 'neighborhood business'. I feel comparing ICOs -- which usually consist of a team you've never met asking you for money for a product you've never seen -- to an established neighborhood business interested in raising capital for expansion of a proven business model is comparing apples to oranges.
Won't take long for the crooks though. Most government regulations are introduced in response to abuse and everywhere they've been rolled back, the abuses come back. No matter if in finance, in taxis (e.g. Uber's surge pricing), net neutrality, whatever.
