> but that doesn’t make those actions unethical any more than governments explicitly legalizing something makes it ethical

That is, sometimes, sufficient.

If government says ‘seller of a house must disclose issues’ then I rely rely on the law being followed, if you sell and leave the country, you have defrauded me.

However if I live in a ‘buyer beware’ jurisdiction, then I know I cannot trust the seller and I hire a surveyor and take insurance.

There is a degree of setting expectations- if there is a rule, even if it’s a terrible rule, I as individual can at least take some countermeasures.

You can’t take countermeasures against all forms of illegal behaviour, because there is infinite number of them. And a truly insane person is unpredictable at all.
