Orest,
Yes and no. If this was a real world clip, then I would agree 100%. However, I think your post assumes that everyone who flies here is post-solo or beyond in terms of their training, and that just isn't the case.
My observation is that 99% of the people that are here are here for the right reasons, however, not everyone within that same 99% are necessarily executing at the post-solo student pilot level or beyond. As a result, the nature of the errors that are made here don't always reflect the errors that are made in real life.
That doesn't mean the recordings aren't valuable, and that we can't all learn something by listening to them, however, I disagree that this is a case of a pilot knocking off the rust here rather than out there (which would be a good thing, I agree!). Instead, this is a pilot still forging the metal....it hasn't even had time to get rusty yet

This is a pre-solo student who was just not familiar with the airspace in which he was flying. You are right, though, it's still valuable to listen to, and we can all learn from it.
I actually had a Bravo violation myself (r/w) well after I got my PPL. This recording definitely took me back to that, and in that sense, it did make my few remaining hairs stand up. In my case, it was excellent evidence of the accident chain theory...a seemingly endless list of small factors that all added up to a big mistake. For more info, check Leg 7 on this
