Personally I disagree with most legislation designed to protect grown adults from their own stupidity, greed, gullibility etc. Obviously minors are a different matter and I never made reference to any of the sorts of things that you mention above so I'm not sure what prompted you to go off on that tangential rant. Ultimately I believe that grown adults should be allowed to do whatever they choose as long as it does not harm the person or property of other non consenting individuals. It may harm themselves but that is their choice. However I realise that we live in a society that does not generally hold the same views as me so I accept the laws that have been enacted that may circumscribe such freedoms and work to change those that I feel are objectionable.
