The trouble with your first point is that UK democracy feels like this:
* Vote winner — your fault, don’t get to complain
* Vote loser/2nd party — you lost, suck it up, don’t get to complain
* Vote 3rd party/spoiled ballot — you wasted your vote, don’t get to complain
* Didn’t vote — you must be OK with any outcome, don’t get to complain
* Found new party — how interesting, let’s invite you on TV even if you got 249 votes total (Lord Buckethead), but anyone who voted for you still threw away their vote
* Left country — who cares, certainly not the council who is supposed to send you a postal vote (happened to a friend of mine in the EU referendum, would’ve voted remain)
