I don't understand why.  It's a simple matter that is clearly
described in the Emacs user manual, for this very reason.

Quite a few development tools use databases that need to be generated
when you start working on a project, and then regenerated from time to
time.  This is quite routine in any sizable development project, and I
think many developers (a.k.a. "Emacs users") are familiar with this
and won't be intimidated by the need to generate TAGS.
