I would like to note that virtually all beginner text books I've seen spam 私は at least in the beginning, so I don't think these examples are much different from what they teach beginners in school.

I was also thinking about it and decided that having 私は a lot helps learners learn when/when not to use the particle は. When you state 私は to start it helps remind you that I am the subject so you don't end up saying things like 犬は好きです when you mean to say 私は犬が好きです。

More advanced learners may have forgotten, but particles are super confusing when you just start out.

Just a thought though.
