One-man game projects exist (Undertale and Stardew being some of the most notable recent examples, though obviously they aren't exactly obscure). Even then, companies and individuals function identically for the purposes of this discussion, so that's not a meaningful distinction. If it makes you feel better about the example, though, think about authors instead. Do you not see any value in being able to know that the Twitter account for the author of an obscure series of novels does in fact belong to that person and not an imposter?
You seem to be confusing "I don't care if certain accounts are verified" with "the verification process doesn't work." I'm not really sure why, given how obviously different those are, but that's very much a mistake.
There are very, very few people in the history of the world that are actually known to a majority of people. I'd be willing to bet that every single example you can provide of somebody that you feel should be verified actually is not, given how rare that is.
The internet didn't exist before. The internet made famous people even more famous by exposure.
