Also i am not sure but i think that at least for low energies we have only a finite number of divergences, in case you increase the energy scale then the infinite terms become relevant and spoil your prediction.

But the problem is that every time you bring in a new interaction that is required to patch up the divergences, you need to fix the

The way out is of course to treat the theory as an effective field theory.

This much should be aparent just from the fact that Newton's constant is dimensionful. Just as we don't expect Fermi Theory to hold in the infinite energy (zero length) limit, we shouldn't expect gravity to hold in that regime either.The way out is of course to treat the theory as an effective field theory.
