The "no solution exists because the voting blocs conflict" problem is inherent and specific to democracy. Other forms of decision-making have their own faults (e.g. absolute autocracy is extremely sensitive to a leader being just genuinely insane, foolish, or blind to the consequences of their choices; consider Nero), but democracy is special in that it can genuinely produce irrational results despite every participant having a rational position.
My point is that the collective decision is foolish, even stupid, despite no individual person needing to be in any way bad or wrong. I do not need to invoke ideas like traditionalism or nostalgia, even though those things are serious albatrosses around D&D's neck. I don't even need to invoke the "people want X, but they refuse to pay any of the costs necessary to get X" problem, even though that is a problem.
All I need is the plain and simple fact, demonstrated handily with an actual known problem WotC faces, that irrational decision making can result purely from conflicting desires across different factions within a group of people. Even when you demand absolutely rational voters (a lovely but entirely false expectation), you can still get voting results that are logically impossible.
