It'd be practically impossible to stop buy backs. Even if the US government tried to do it, the corporations would have their little shelf companies in tax havens like Ireland buying back the stock for them.

In this episode we hear Jeff Bazos is looking for a $5B Government stimulus for the Space Launch Industry to keep ticking over during the crises. Hey Jeff how about you use half of that $10B you pledged to fight Climate Change to keep your industry afloat instead? You know? Capitalism? Why are you happy to not pay meaningful tax but donate money which will be used to dictate how others live their lives (not you of course) and at the same time look for handouts from taxpayers to keep your industry viable?
