Very often regulation starts lean, then inevitably some assholes take advantage of it to their profit, so the regulation becomes more and more specific and complex. Rinse and repeat.
It starts at individual level. In France, health insurance providers started reimbursing eyewear, with a rule "one pair of glasses each 2 years". Now everyone buys new glasses every 2 years, sharp, because "I'm paying for it", even if they don't really need new glasses. Stuff like this make insurance price go up for everyone as a result, which incentivizes you even more to be an abuser. The rules are now more strict about the how much is reimbursed, because people obviously go for most expensive Gucci frames allowed.
