Buying it doesn't necessarily have to mean becoming owner of the physical thing. You could buy the EU by spending enough money with the politicians that you essentially get to do whatever you wanted as if you owned the physical thing without actually having the burden of ownership.

Alright, so given this is your belief, why wouldn't you think that this has already been done, if it's possible? No one felt like buying the EU until in the future? Or maybe, it might actually be harder than you think?
Which again makes sense, the US entire philosophy is "Everything is for sale, if you can afford it, you can buy it", so of course that's what happens now.
However, laws, politics and more is slightly different in the EU and Europe, hence you can't just wave money and get your wave, unlike the US currently.
You have 27 governments reacting to the agenda set by the powers on both hemispheres (defense spending, tariffs, proxy wars, etc) you don't think enough influence has been bought?
