Without getting into the specific point-by-point refutation of this because, some of it is valid, I must first wonder why it is that people assume that every product should fit every person.

My first reaction is how horrible it would be to set up a Google+ account for my dog. I mean, my dog doesn't even have hands! Pulling that back a little bit though, it starts off with "my mom isn't big about the internet."

More to the point, there isn't actually any 'horror' in 'setting up a Google+ account for his mom'. By all accounts, the lack of horror in the actual account setup tells me that it was probably a fairly trivial affair, or even, uneventful. I was expecting something about real name guideline violations or switching accounts being an issue, but that's not the case at all, it seems.

Perhaps the most legitimate complaint (to my ears, your mileage will vary) is that there are non-circled posts added to your stream. The 'promoted' or 'hot' posts or whatever could certainly do with a toggle permission or something for the 'closed circle' types, and I actually thought that there was a way to keep people's stuff out of your stream.
