It's how the (previous) government was able to look like it was doing something about the mental health crisis caused by social media, even though this bill won't fix that at all.
IMHO the argument for "doing something" is one of those things that people are noisy about but ultimately care little about at the ballot box. The risk is that the typically politically apathetic are driven to the ballot box as a consequence of disrupting their habit in order to protest. Most governments do very little that actually directly interfere with people and their habits, COVID was a very rare event and Boris Johnson fell in no small part due to circumventing the rules his own government imposed on the populace. There's huge electoral risk in giving so many people consequence.
Given the numbers at play, I just don't see how you can square the huge internet traffic for pron and the intrusion into their "workflows" against some presumed other number of electors that will suddenly vote for you because you allowed this bill to take effect. Irrespective of the ethics of the subject it just doesn't feel like good electoral statecraft in a democracy. This is particularly surprising given that most UK political parties generally veer away from doing things that might lose them any significant amount of votes.
It's hard to know how it'll work in practice without trying it.
until they can't because they're also made illegal
don't forget this is also the same government that has effectively tried to ban e2e encryption by forcing companies to install backdoors into their algorithms under gag orders
it is no longer (if it ever was) about the children
People no longer start their own forum, but create a Facebook group etc.
I think it speaks volumes of a strong bias in their analysis teams, as well as indictating they're even more out of touch than expected. What they've done is given direct negative consequence to millions of electors in exchange for indirect and mostly imperceivable positive consequence to concerned parents. Personally I don't see a way that ever makes electoral sense, especially given how close the last election was (in raw votes, not seats) and where opinion polls are today (Reform seemingly being considerably ahead, albeit opinion polls are _not_ reliable).
Obviously there's a lot to say about consequence, how the use-case of authentication is at odds with the desire of users to be incognito, how VPNs are considerably better UX; but their use undermines previous legislation like recording host names to help combat extremism, how encouraging users to dish out sensitive id documents online isn't the best habit, how id verifiers are not regulated and often are services hosted abroad. Obviously the biggest negative is that sketchy websites who don't care about being legal will gain considerable traffic, at the expense of websites who are trying to be legit. Children will still probably be able to access pornography and it may just be the case that the pornography is even "worse", yielding the most counter-intuitive outcome.
I'm particularly alarmed that many websites are responding by blanket age-verifying NSFW content. So now reddit resources on mental health, drugs, suicide, domestic abuse, etc are locked behind age verification.
