Just because you can't rob a bank or pollute a river does not mean that the law is applied equally at all levels and, e.g., the government/Fed is stopped robbing our banks through inflation and debt, or the corporations they are beholden to are punished ro polluting and poisoning our bodies and environments.
You'll do fine without robbing a bank or dumping chemical waste (neither of which are profitable in practice now, as well). Meanwhile society is littered with so many small instances of copyright infringement (memes, which usually are not fair use; fan art; etc.) that it's common practice for rightsholders to look the other way - but it shouldn't have to be common practice, it should just be policy.
Also copyright infringement does not physically harm people.
Starving artists might disagree here.
Breaking the law makes a lot of terrible business models instantly profitable.
Imagine I have a uranium refinement company. It is a colossal capital investment and not many companies do it. Law forbids me to sell weapons grade uranium for random people, but it just happens those very people are the ones who are willing to pay a lot of money for it as long as I don’t ask too many questions.
