The 1967 Treaty was born of the nukes in orbit fears back in the late 50s. The weaponization of outer space. The collectivists at the UN and in seems like most of the 2nd and 3rd, and probably 1st world, too, have this idea of our societal evolution, like Pres Clinton, that does not encourage individual initiative to the extent of any one company or capitalist getting a monopoly in space. The entire world is painfully aware that America is so far ahead of everyone else in continental shelf development technology [outer space for most countries] that America could run away with everything, pick all the plums. So they extrapolated to actual outer space and there is the Treaty. America signed it mostly to stop the Russians from orbiting nukes. But the Treaty has to go, now, so we can bust out into outer space. Others are gearing up to develop celestial resources, treaty or no treaty. Others being China, ESA, NASDA, Russia [maybe, but they have a lot of undeveloped resources already], and last and still not least, NASA. Toss in some others who will follow along as soon as possible such as Brazil and India, and you will see that the private entrepreneur will easily get overwhelmed and become insignificant and may be safely ignored ast the Hitchhiker's Guide says.
