If you’re talking about the US, then the laws absolutely exist. They were created to break up companies like Bell and Standard Oil, and are extremely effective,
when used.
But they haven’t been used for decades, because regulators have decided not to use them. There are of course many reasons for that, including political pressure and regulatory capture. But to say the laws don’t exist, is just wrong. They exist, they just haven’t been used for a long time.
Also writing law to obligate enforcement is tautological. All law is meant to be enforced. Who’s gonna enforce the enforcement of enforcement laws? And why would they not be subject to same pressures to under-enforce as well?
> Concluding that regulation dosn't help when what we're observing is non-enforcement is a bit disingenuous. If I'm being charitable.
Why do think I came to that conclusion? My comment argues quite the opposite.
