Sometimes what's good for the 1 person isn't good for everyone.
For example, if a bank starts giving out 0% interest 100 year mortgages (with some fine print that gives them some obscure revenue source to make it possible for them to make such an appealing offer) the bank should still get in trouble in my opinion if the consumer isn't informed about how they're getting such an amazing deal, because you're removing the consumer's ability to make an informed decision.
