Governments chosen by a first-past-the-post system can barely be considered democratically legitimate, if at all.
That's unlikely to be true, because there would be way more viable parties. Maybe you would indeed have a supermajority of left-of-center parties but you can't conclude that they'd all have the same Covid restriction policies as the current ones.
Ranked choice (any form, not just IRV) voting systems without proportional allocation (whether multimember districts with STV, mixed member proportional, or party-list proportional, or something else) do not significantly increase the number of viable parties.
On the other hand, I'm amazed that 5% of the population voted for the People's Party of Canada -- a party which had no hope of winning. This absolutely split the vote on the right enough to make the CPC lose seats.

FPTP vs. good election systems is not a trivial distinction like this, so your analogy is invalid.
Your comparison to North Korea casts doubt on your sense of proportion.
The the proposal of the convoy occupiers is that their organization picks a committee to run the country. That's a significantly less legitimate government with absolutely no claim at a mandate.
The best we can do is look at opinion polls, which suggest that most people want to get rid of most Covid restrictions, but also don’t support the trucker protest.
