The overwhelming cost in these projects is always engineering salaries. These companies are making the calculation that they can throw shit (rockets) at the wall (into space) carelessly to save money by wasting more material to avoid paying the salaries of people that could think through the design more carefully and come up with something that will have a reasonable probability of working the first time.

And you can attack that issue by a combination of penalising companies that create debris and rewarding those that remove it under a capitalist economy

Add this to the insurmountable pile of things we should theoretically regulate but never will because of regulatory capture.
