Sure.  Illegal drugs have been survivng and flourishing for decades even after they instituted the war on drugs.  Illegal immigrants (how a human being could possibly be considered "illegal" is beyond me) have been continuing to flow across the border and work and live prosperous lives even as they are being hunted down by ICE and Republicans.  Illegal filesharing (how can an idea be "illegal" and how can moving and copying electrons be considered a crime?) has been continuing to go on inside everybodys home network ever through bittorrent and other means ever after they crack. Oh y. eed down on napster.  Oh yeah, and few people bother to come to a complete stop ar at stop sign.
