As dot said, it's a common topic. The simplest answer is that it's better to take away the motivation for the crime, rather than enforce ineffective punitive measures. It's why pro-life people rarely make sense to me; they also frequently dislike contraception and comprehensive sex-ed. Wouldn't it be better, if you dislike abortion, to prevent the need for it in the first place? But I digress.
The reduced motive for economic crime is obvious, as for things like rape, assault, etc. these things are often the result of patriarchal or white supremacist cultures, toxic masculinity, etc. which the state and to a greater degree capitalism upholds. It's easier to sell us shit when we have discreet genders, interests, and levels of aggression.
This is also why I have no use for anarchy that ignores gender and race issues.
