I'm not sure what you mean. You're right that the two are usually intimately linked. What I've found by blocking tracking is that as a result of this intertwining, blocking tracking usually also blocks the advertising engaging in the spying.
I don't use an adblocker. I block tracking. It's pretty nearly as effective as an adblocker, so that seems practical to me.
"block tracking, not ads" - given the strong links between tracking and ads, saying which one you intend to block is nothing more than wordplay. Practically speaking if you block tracking you likely also block more ads than you don't, whether that is your intent or not.
