Why aren't pop artists convinced by their own songs?

I'm guessing that if you require a trapeze, a bunch of tape strategically placed instead of clothing, and a bucket of water in order to perform your song, your song is probably not very good.

Now, this is all speculative. I know nothing about Pink's music, because she started releasing albums after I was born and is therefore obviously terrible.

However.

The biggest band ever stood on a stage wearing matching suits with ties and sang their songs. And that's pretty much it. They did not do handsprings, no one skanked it up. The extent of the choreography was "Oh, maybe we'll both sing into this one microphone."

This was better. Among its other virtues, it wasn't demeaning. Also, I think people may have listened.
