A token is just a token, who uses it how and why is not intrinsic in the token itself. Stocks and bonds have been tokenized, why are those not scam? There are lots of tokens representing different things, economic models and with very different histories following their creation.

Ah that's very easy question. Stocks and bonds have very heavy legal framework you can lean on in many situations. It doesn't mean you can't lose - stock investors lose they money all the time - but at least some scenarios are covered. With token nothing is covered, it's basically a naked bet on issuers and their ability to deliver. I don't say never bet - adults can decide for themselves - but if you bet, do it with open eyes.
