I think laws become less relevant over time for many reasons. There are entire books written about silly and obsolete laws, e.g.:

The age of a law or regulation is likely a strong indicator for its relevance in modern times, especially if it’s regarding something quite niche.
These laws are neither silly nor obsolete. That's a distraction.
So is the age of the law, for that matter; courts don't waste one second on the topic. Settled law is settled.
