Do you have a cost per ton figure for waste disposal in outer space? What price for minerals do you need to cover variable cost, much less the initial investment? And if colonization of the moon made any sense, why aren't there colonies on Antarctica? That's a much less hostile environment than space, and far cheaper.
If it were cheaper to send toxic waste into space, the launch vehicles would be leaving Earth daily. It isn't. It's a pipe dream.
It's going to happen.
The reason there are no colonies on either are UN treaties. Nations are prohibited from having permanent colonies or from doing resource extraction on that continent.
Outer Space treaty prevents ANY private property claims offworld. Otherwise there would be a booming industry.
As far as price per ton of materials, give me 20 billion dollars in startup costs and I would be able to undercut EVERY mining operation on the planet for precious and semi precious metals for the next 50 years.
In the process I'd also give Earth a new moon and a nice close in base for cislunar and HEO operations.
Considering the fact that NO ONE has a solution for long term high level radioactive waste storage going, price is almost irrelevant.
But for 100 million dollars I could put 500 tons of high level nuclear waste into a solar orbit that would decay and drop it into the sun. Look up the SEA DRAGON booster.
Space is a permanent solution for a lot of problems.
Space mining is economically possible. The technology was mature enough 30 years ago and the business numbers add up. If anybody is actually interested enough to try to figure out how to do it rather than why to not do it, a discussion is possible.
