Whether it's a issur lav or bittul/issur aseh, chaza"l had no ability to instruct us to actively engage in a practice that is contrary to din torah. Period. 

This isn't entirely satisfactory, though, because they *wouldn't* be
telling us to eat chutz lasukah, they would just be forbidding us from
eating in it.  We could still either fast, or eat only achilat arai;
neither are prohibited min hatorah.  So it would still be a shev ve'al
taaseh, sort of.  If this is the best answer we can come up with, it
will have to do; but there's still a point in looking for a better one.
