That's because it's not a prohibition on individuals as it wouldn't be constitutional. It is a prohibition on issuers, who can face civil and criminal sanctions while also having the entire offering rescinded retroactively. The government effectively achieves what they were going for either way. (A strategy to curb/steer any behavior is to regulate the intermediary.)
So if you, the individual, want to lie and constructively get into a private offering and be quiet like an actual wealthy investor, there is no consequence except you might overextend yourself due to the minimum investment amount set by the issuer.
Regarding law, the government can still place any number of restrictions on issuers, but the current law does not work and I think it can be argued that it "chills speech", and doesn't make sense. Always remember, the entire SEC is a creature of the New Deal, and although this is heralded in our history books, most of the new deal was quickly declared unconstitutional, and the rest wasn't challenged. Here we have something that doesn't affect rich people and they might not be aware of it, while issuers are prohibited from marketing to poor people and poor people generally aren't aware of it either. There are just a few upper middle class people that get to say "what the heck is this"
