you admit you don't have something magic and irreplaceable

It seems like you're dismissing businesses that can do this as somehow not innovative, which is definitely not the case.

Many businesses are simply not designed as a business to benefit from growth through money (aka "buying users"). It's quite difficult to do so, even though we know it is possible, that others have done it, and that others are doing it right now.

Just because something is simple does not mean it is easy.
