As a bass player you have to lock with the drums (and they have to lock with you) but, sorry, all this "we have to play to the level of the drums" is rubbish.
If your band has a drummer who can't vary his volume fire him and get a drummer who can play properly.

Actually it makes perfect sense, I just don't think you are reading it the right way. Unless the drummer is using an electric kit the loudest thing acoustically in the rehearsal room and/or on stage is the drums. Irrespective of whether the drummer can vary his playing or not - all that means is that if he can, then everyone can turn down a bit. If he can't, then everyone turns up a bit. But the volume that everyone needs to match is that of the drums. If the guitarist is too loud, tell him to turn down.
