Has there been the fabled second spike after VE day? If there's no second spike three weeks after the protests (although no doubt the clowns in suits will twist the figures to make it look as if there is one), then I think it's time to scrap most of the restrictions. We have NOT "practically gone back to normal" - we are still very much not normal. As far as I'm concerned, it's not normal until that wretched social distancing is scrapped, and we're back swimming, attending church, in the theatre, playing recreational sport.
We certainly went from "roolz" to "common sense" very quickly: no doubt because of one Dominic Cummings. Also, calling them "guidelines" is rubbish: the word implies that they are optional.
The government is being highly tactical with what they actually have the power to enforce. They can't really enforce banning houseguests, and social distancing: they know that, we know that, they cut their own resources to do so. Early on, they tried to fool us that they could, by having the police make token appearances. They're concentrating on what they can enforce, such as forcibly keeping non-essential businesses closed, so people can't go into huddled situations. I think the government is waiting for us to break social distancing ourselves, so they can test if it really matters, rather than telling us we no longer need to keep it, because they don't want to be accountable for saying "you don't need to do it any more"; they're probably quite glad about the protests, they just had to be heard to say "don't go".
From the underhand and gaslighting tactics the government has been using, I think that if we're too obedient and docile, they'll keep restrictions in place for longer. I'm sure also a major reason for the forthcoming "enforced mask wearing" is a cynical test of public obedience. Why bring it in so late on, especially after all the dithering and mixed messages about masks?
This whole thing is the biggest government gaslighting exercise ever, and a textbook for future governments on running a nanny state (I'm surprised we haven't heard that phrase much) by deception.
