Not living there doesn't matter a jot.
Sliding doors moments happen in politics all the time: PR voting systems under Blair, Brexit under Cameron, the Scottish Independence referendum. These things happen.
At the moment, the SNP is in disarray, Alba is held together by Alex Salmond of all people and all baggage, and Labour is on the offensive (see the groundwork being done for the potential Hamilton by-election.)
Opinion polls have shown the Yes vote tanking month by month. Cost of living is far more significant than Independence.
You won't get another referendum under Sunak, we all know that.
You won't get another referendum under Starmer, we all know that.
So what's left?
You’re focussing on the wrong things.
Yes, the SNP is holed below the water line, but support for Independence and support for the SNP have not always neatly aligned. It is possible that some who drift away to Labour retain support for independence. This then becomes a problem for Labour.
Furthermore, whenever polls have looked at independence support in age groups, younger groups have shown the highest support for independence, older groups the lowest. And another change is that women used to be more cautious on independence but there is now more gender parity. One poll recently put independence support ahead of SNP support. It used to be the other way around. The demographics suggest it is possible that independence support peels away from the SNP. (Not to the Alba Party. No idea why you mention them, they’re an utter irrelevance. They have no MSPs and the only Westminster MPs they have were defections who will lose their seats at the next election).
The SNP has been the de facto leadership of the independence movement, but since the 2014 referendum dropped that ball. It has not made the independence case, focussing instead on being the government. Nobody (credible) picked up the ball. That could now change. One thing that Kenny McAskill is right about (much as it pains me to say) is that an independence convention (like the devolution convention of the 90s) could take things forward. Of course there is not the sweep of civil society institutions (NGOs, trades unions, church groups) in favour of independence that there were supporting devolution. But peeling independence support from the SNP could change that.
And of course referendums are not the only way to go. For example, for decades the SNP policy was that if it won a general election that would be taken as a mandate for them to begin negotiating independence. While Prime Minister, Margaret Thatcher (not believing it would happen) expressly supported that view.
The growing perception (actually incorrect in my view, but never mind that, it’s a perception none the less) in Scotland, even among non supporters of independence, is that Scottish political culture has diverged from that of England. Not just the Brexit vote, but things like Boris Johnson being voted Prime Minister. I had conversations with many people who had voted No in 2014 who maybe hadn’t quite travelled to Yes, but who saw Boris Johnson as a weather vane of the different political cultures. I was speaking to a No voter on Saturday who remains a No voter but who sees Suella Braverman in the same light. As I say, I think that’s a simplistic reading, but it’s a widespread one. And while it takes root, the genie of independence remains out of the bottle.
After the ‘79 Devolution referendum, devolution seemed it would “never” come. The ‘97 yes vote proved that wrong. 18 years is a long time in politics. Never is even longer.
