The big problem I see with all of the methods you describe to avoid matching is that they are one-offs. A mask obscures your identity; you are attempting to make your face indistinguishable from anyone else’s. But alterations like (most of ) the ones you describe just create a separate identity—more akin to plastic surgery. This is great if you are trying to avoid linking yourself to a former identity, but not as useful for trips to the grocery store, where this new ID will be tracked and monetized.
My suggestion would be to wear something that hides your gait, rather than alters it. A burqa might work. Or ride in the motorized cart.
Regarding the goal: Personally, I find the tracking by the grocery store helpful enough (given the incentives they set up) that this is among my areas of least concern for tracking. I appreciate, for example, having novel grocery products that I might like suggested. This is different than for, say, televisions, where I discover that I am artificially dissatisfied by learning about newer features. A key differentiator is that I am constantly buying new food, so there is no pressure to buy something vs. remain satisfied with something I already own. Of course, other areas where gait tracking would come into play might provide a different value profile for me.
