If "having a government identity" was a solution to the identity problem, it would be solved.
It is not solved.
That is at most the beginning of a solution to the problem.
And in practice, it is little more than the beginning of the problem, as the government's definition of blindness is very unlikely to be a precise match to "has problems completing our visual CAPTCHA", and if multiple governments have standards there is no chance they will match.
Do not underestimate the resilience and resourcefulness of scammers. They aren't just some individuals here and there who decide one day that they could make a couple extra bucks spamming people, and just sort of start sending out whatever scam strikes their fancy. They're international businesses with engineering teams, and a constant feed of low-level operatives who can scam governments about how blind they are if the governments leave any hole in their system. They're thousands of people dedicating their full human-level intelligence to the task of defeating your system and extracting the value from it. They are not as easy to defeat as "let's just put the obvious certification in place", for the same reason that the CAPTCHA problem isn't solved with "Let's just issue everyone official identities".

I don't know about your country, but in my country the government is pretty keen on avoiding abuses of the benefits system. After all, a blind person gets tax breaks and cash benefits totalling about $5000/year.
So the existing system is used to dealing with financially motivated adversaries. I doubt the additional financial motivation of being able to bypass hCaptcha would mean much, in comparison.
