The comparison with the prohibition of culturally unconventional psychoactive substances has been made repeatedly on this forum. Not only are they also bad laws that are staying on the books in large part because of sunk costs, they similarly were intended to enforce a "purity" of minds and protect vulnerable young people against the dangerous self-indulgence of desiring and attaining pleasure.White sea Snow Elf wrote: Thu Apr 03, 2025 3:45 pm Actually, I am worried about a situation. A friend of mine who studies law once talked to me about this topic, which is the "sunk cost of bad laws". Just like someone keeps investing money in a business that is destined to not make a profit, this concept can also be applied to law. If too many people have been punished or even lost their lives because of a certain law, then even if the government wants to reform, it will be difficult to carry out, because a lot of resources have been invested, and a lot of irreversible and difficult to compensate results have been caused, so they would rather continue to invest resources with a gambler's mentality than start reforms.
He also talked to me about the failure of Prohibition and the failure of the war on drugs, which are actually manifestations of the "sunk cost of bad laws", and he believes that the age of consent law faces the same problem.
I've been involved in the successful campaign to legalize cannabis in my jurisdiction, and I'm still passionate about psychedelics legalization, especially psilocin (shrooms), LSD, and MDMA... most of my allies would add mescaline (peyote) and DMT (ayahuasca). One thing I can say is that the law will never change without widespread illegalism.
We should keep in mind that no matter the costs to society of changing bad laws, it's always possible. The abolition of slavery is an extreme example. Such changes generally depend on paradigm shifts in cultural attitudes.
