I think it's human nature for the novelty of anything to simply wear off.
It's like a boy who gets a new ball for his birthday - for a week he's kicking it about all over the place all day every day, but by degrees, the novelty wears off, and it becomes normal again.
The same applies to the mass as to the individual.
When Covid first appeared, and everyone was locked down, it not only was all over the news, it was the only news, for weeks on end.
Now, the novelty has worn off, people are simply learning to live with it, and trying to get back to as much normality as they can, which is human nature.
So the government will find it increasingly hard to obtain the public's co-operation in voluntarily subjecting itself to lockdown, which is why they are making less of an issue about it.
The government is not stupid enough to try and be heavy-handed, and look foolish when it is ignored, it is taking its foot off the pedal where it can, and slowly letting people mix and develop immunity or, as was always the case, simply be ill and get well again.
Yes, I think forced lockdowns have had their day.
