Perhaps it is a simple case of some businessmen buying the kind of legislation that benefits their business plans.
Neither Russia nor China will be bound be this idiotic treaty, but as always the US will honor it, and no US HQed company will be able to compete.
It is as simple as a superpower - see above - just doing it. The US was long a nation and country of exploration, but by 1974, we had become a consumer country, no longer interested in anything beyond our collective navels. every innovation was labeled “too expensive” and “we can’t afford it” ... “there are homeless to feed”, or now “there are refugees to take in”.
To really explore, data needs to be collected and analyzed. Data collection is easy and cheap, but analysis is difficult and expensive; along the way, various oxen tend to get gored - so no one analyzes the data now, they have careers to think about.
What data does get analyzed is done to fit a preconceived notion, anything outside of that is discarded. The famous example of this is when the first Mars Lander sent back its first pictures from the ground to the waiting press - after the techs had fined tuned and color tested the monitors, the first color pictures came back -— the sky was an azure blue and the ground had green lichen on it -— quickly, the presenters twisted the color settings until everything turned red as it should be ...
During the first Bush II term, he proposed the Moon to Mars program - the various seminars were carried by NASA TV. The upshot of the conferences for bright young people wanting to get into space exploration was go to some other country - opportunity here was very limited to non-existent. This has not changed, but worsened. We produce no engineers anymore, just software developers and CEOs.
All you see now is the dying embers ...
