Hey moron, as I just told you:
Plenty of utter crap has been sold by the overly regulated banking industry. Regulations do not prevent or repair damages from scams, either.
You just want to blame anything else but yourself.
Of course there is crap in traditional investments, but not to nearly the same percentage that there is in BTC Securities. I have dealt with plenty of both types of investments to know that most of the crap is in BTC Securities.
Perhaps we need to start getting all those that want to introduce a security to have to put up insurance that will protect investors. If we all were omniscient then we could exercise due diligence. We need some sort of system of trust that can be relied on. Regulations do prevent scams as we would have much more scams if we did not have the threat of sanctions. I am not certain what the perfect system would be, but letting it simply be a free-for-all is not the solution.
The system is not yours to "let." It does not need your permission. You are hiding behind collectivist language: "we need to," as if one individual's conception of a greater good is justification for the use of violence against his neighbor. Take the initiative and do it yourself! It's disgusting that you would substitute hard work for laziness at the expense of others. You are worse than the accused scammers; at least their victims had a choice!
Some estimate that the ratio of scams in Bitcoin is not that far off from the ratio of scams in the traditional financial institutions:
http://trilema.com/2012/the-bitcoin-drama-timeline/Considering an average monetary mass of 7mn BTC for the interval, the aggregate of theft, fraud and stupidity registers as about 18%. Considering fiat monetary mass is somewhere on the order of magnitude of 5 trillion USD, proportionally the same levels of loss would come to about 900 billion total or roughly 50 billion a month. Shockingly enough, this figure is not quite that far off the mark (provided we discount government actions from the stupidity label).
