I am not @MrDibble, nor am I authorized to speak on their behalf, nor do I even play them on TV!
But speaking to your question for myself, I see the problems with 100% of anything is that we’re, sadly, human. And we are extremely prone to factionalism. So even if you start with 100% of anything who all agree on the same goals, they may not want them in the same order.
I mean, and back to the USA specifically, Democrats are a pretty broad tent, from actual Socialists (which is NOT a bad word to be clear), to Green First individuals, to social equality first, to “mainstream” Democrats, to extremely conservative democrats, and even some reluctant post-MAGA former Republicans.
The moment MAGA is out of the way (or long before, if you look at certainly elements such as the “undecideds”) the factionalism rears it’s head and and as a result, nothing gets done.
The reverse has also been true, I mean, look at the whole Speaker of the House issue! I’d argue that the Republicans, Tea Party remnants, and MAGA are overall far closer than the various wings of the Democratic party, but they couldn’t wait to apply purity tests to their own, even when it made them look like squabbling children to everyone else not insulated by a partisan news bubble.
I don’t think it’s healthy mind you, but I think it’s entirely too human, and that’s one of the reasons I feel like having a certain degree of opposition is useful (see my 70/30 comment above) especially if said opposition is at least rational.
IRL though, no, it’s NOT rational here, and we are far from being able to achieve @HMS_Irruncible’s worthwhile goals that enable said irrational actors to dominate.
Minor niggles with the statement of “the will of the people, which shouldn’t be overridden” especially in a world where his next (IMHO fully accurate) statement shows the role of corporate and profit focused media isn’t putting a huge weight on the scales remains. I do think having guiderails that protect minority viewpoints from the will of the majority are by and large a good thing, but acknowledge everyone draws it differently.
IE if 50.0000000001% vote to require the rest of the population to wear Giant Purple People Eater Masks (going low stakes here so I don’t step on anyone’s private crusade, unless you’re super pro-PPE) I’d like there to be provisions to protect the rest. But our current bar on Constitutional amendments are far too high IMHO as well.
