It depends on what you mean by 'strong regulations'. Regulations that are on the books should be enforced as written. In that sense I agree. But it doesn't mean that we actually necessarily need all the regulations that are on the books to stay on the books.

Eg, it would be perfectly fine to make insider trading legal by law. (And in fact, the definition of insider trading in the US differs a lot from the one used in France. So there are lots of things that have long been legal in the US that would have been illegal in France, without the economy collapsing.)

I agree that random enforcement of some regulations but not others depending on the whim of the executive is less than ideal.
