What I am suggesting is more along the lines of agreements among all the "powers" that can actually get to the Moon and might potentially get in each other's way, degrading the opportunities for all. Things like zones that could be kept clear of EM emissions in certain frequencies so as to facilitate astronomy.
As for mining, etc., I think we already know how destructive that has been on Earth. So, yes, it seems like a good idea to not have just anybody that can reach an asteroid be able to do whatever they want with it, without considering such things as scientific investigations being conducted before disruptions.
And, what about some company deciding to move a large asteroid into LEO "on the cheap" and then going "Oops, sorry about that, Paris!" when it "accidentally" goes off course and actually hits our planet?
"Anything goes" is not necessarily even safe for people who never get involved in the space industries.
