Because primals, bad.
Primals drain aether (lifestream)
Eorzeans need aether (life).

Some plot device like that.

Its not really a negotiable point as Eorzea depends on aether.
But the beast-races being not so smart(?) worship and are summoning Primals (who drain aether).
So there's no middle ground for talks.
