Some places that would do face recognition would not do gait analysis, and so you defeat those. Additionally, if you prevent them from doing face recognition and they can do gait recognition, they will be forced to use gait recognition, which is likely more expensive or less reliable, which will limit their ability to do it in a widespread fashion or cost them more to do so.

Think of it like cloudflare in reverse. The less of your identity you passively provide cloudflare, the more they will hinder and punish you and your CPU before letting you through to the website. If they make it burdensome enough, you may give in and give over your private data or not access the website at all.
