The only countries even capable of enforcing launch bans stand to gain nothing from them because it just makes launching their own payloads more difficult. There's like ~10 or so countries who are readily launch capable and even less with the military capability to put any pressure to stop foreign launches.

Who's going to regulate? Regulation only works when someone has the power to enforce them. Right now the people with that power aren't the most agreeable. And flexing it is either antagonizing western allies or a declaration of war.

The UN is fundamentally and terminally flawed and always has been from the very beginning as ruse for what has always been a facade of “America’s” control of the world.

It is why the UN lair is right on the East River, a proverbial stone’s throw away from Wall Street, Madison Ave, and Broad Street in the heart of the American Empire of world domination.
