The most important part of an exercise routine is sticking with it. Doing a volume program is way, way healthier than doing nothing at all. I find that the aesthetic gains make me more motivated to go to the gym than when I was just increasing the total poundage of weight I could move in one rep.

Totally fair, I'm more interested (and thought this thread was about) figuring out the optimal ways to do things, compliance being ignored. Considering compliance changes a lot of things.
