Earlier quoted context omitted.
Buying a company that owns an asset or holds a license is a reasonable way to obtain said asset or license. Nothing wrong with that.
If you're talking about a license in the sense of a right, like a copyright or patent license, or a license to drill for oil somewhere, then yes. But this is a license in the sense of regulatory approval of a specific organisation, which is not something it's proper to buy and sell. You can't buy someone's driving license, gun license, medical license, license, etc.
But how does regulatory approval work with institutions? Institutions are ever changing, and like the ship of Theseus, eventually the original company will replace all of its employees, management, and even processes.
So what triggers a need for renewed regulatory approval? If the original company switches out 50% of its workforce it can keep its license, but if the owner changes suddenly the license is invalid. How does that make sense?
