I specifically mentioned the "market price". I don't really know how these US congress persons work, and you may as well imply that the idea that they "represent" you is as much bullshit, as Musk-assigned board member represent real shareholders (and I have no problem with this implication), but there surely must be difference (and it isn't even the fact that you supposedly voted for them): unlike congress people, who can decide whatever they decide in the USA congress, the board cannot decide the market price. At least, usually. Every shareholder wants market price to be higher, and the board members are supposed to try to achieve that, but they cannot appoint the price, they simply have no such power. By definition, it's the market who decides that. Otherwise, it isn't clear, what the "not so low that the government gets involved" is even supposed to be. I fully admit that I don't understand how this works, so this may sound silly, but it would seem fair to me that since the moment company became public, nobody ever can undo that, because microscopic pieces of that company legally belong to some random people now, and they can ask whatever price they want for their share. If anybody makes them sell at any price that's less than what they want — it's a robbery.
Now, I can kind of imagine the way this could be worked around. E.g., there must be some way to liquidate the company, and hence there must be way to execute the merger regardless of what shareholder minority thinks of that. Each company gets supposedly "fair" valuation before the merge and old shareholders get specific amount of "new" shares in exchange to their old shares, which is kinda like getting the cash, so here we go. I mean, I still cannot explain myself, how this can be considered fair and legal, but I suppose there is an explanation. But even this way, the natural way to do that seems to use today's market price. So even if 51% belongs to 1 person and nobody else can decide anything (so, he basically IS the board already), how can this person offer shareholders anything else than the market price for what belongs to them? This doesn't make any sense to me. It sounds like a robbery, plain and simple.
