I do agree that this would be a great PR move. Especially as we've seen Bezos grow his wealth by $65bn in the last 4 months[2] or Elon by $44bn (more than doubling) in the same time frame[3]. But the practicability is also a little naive considering that these numbers do not equate to liquid cash that they have available. Though someone like Gates has much higher liquidity than Bezos or Elon.
But it is interesting. Maybe if my metric catches on someone will build one (or another mega science project) :D

[0] One could even make a concession and let the wealthy choose among a list of approved charities/projects to spend the taxed money on.
Not really. They use the "mob"'s roads and banks to make their business work and store their wealth. They use the "mob's" courts and police to protect themselves and their property. We live in a society, if your worry is that they are too powerful for them to participate in that society (e.g. because their power would let them hide their wealth away), then that just makes the ridiculousness of their wealth all the more apparent.
I mean, super science mega charity is going to have worse conspiracy theories. It's going to be the Gates foundation stuff mixed with the LHC stuff.
Like he's opening a portal to hell to mine energy from or something. No wait that's DOOM.
I mean, first of all, mega-science is just as prone to grift and mismanagement as any other type of mega-project, and far more so than vaccine programs or malaria treatment. And just imagine, what would the absurd conspiracy theory nuts say about a supercollider?
Of course, hey, wait a second, Gates and/or the Gates Foundation already do this (e.g. TeraPower, e.g. CFS), so your whole line of reasoning that it'd have considerable PR benefit is proven false. Fortunately the Gates Foundation isn't very motivated by PR.
So no, I didn't quite prove the idea of its PR value false. Conspiracy nuts will always find a reason to consider anything made by some people or groups as suspect or outright nefarious, no matter how straightforward it is. but foundations oriented towards education, medical research and healthcare for the developing world are easily much more prone to that kind of narrative manipulation than a fixed, specific and extremely complex scientific device that will be used for a more limited range of possible things over a certain period of time.
The same applies to the differences in opportunities for graft and corruption between the two: Dishonest contractors and consultants could find ways to milk a privately funded super collider project during its construction and even during administration, but the scope of their opportunities would be fairly limited beyond a certain point, especially if the (presumably not stupid) billionaire funding it is keeping an eye on details.
Imagine on the other hand how many opportunities something like the Gates Foundation could offer for bad financial administration down the decades after its creator and main benefactor dies of old age or etc. Most of the collider's budget as covered by a billionaire in my scenario above will be a single sunk cost spent during a very limited period of time. The endowment of a giant foundation with flexible goals can on the other hand be managed (or mismanaged) ambiguously for decades.
The two things are not the same either administratively or philosophically.
Not to mention that they would be paying for an immense and unambiguously good scientific gift to posterity that would be free of all the complications, interest conflicts, mismanagements and so forth that come with building a mega-charity like the Gates Foundation (the conspiracy theories around that alone have been absurd, despite all its excellent health programs for the developing world).
It's always hard for a person to say what they'd really do if they were in other shoes, but if I had the sort of fortune that a Bezos or Zuckerberg has and especially with the relative youth of these guys, it wouldn't be hard to convince myself to make such an investment.
The Large Hadron Collider cost somewhere in the neighborhood of $10 billion dollars. Bezos alone saw his net worth grow by a multiple of that in 2020 alone. This huge cost would barely dent anything else they're doing or funding and in no way dent their personal quality of life.
I'm not at all arguing that they owe something like this to the world, or trying to paint any kind of anti 1% resentment, just pointing out that paying for this doesn't even seem like such a bad idea for people like them and their image for posterity (something always important to most billionaires).
The top four or five billionaires in the world could even cover most of ITER's much larger budget without permanently or seriously denting their fortunes.
