If you pay in cash, wear a mask, and buy your token scratch card a couple counties or states over it's as close to anonymous age verification as possible.

Admittedly it's still more intrusive than the status quo (what if the cashier has a photographic memory? what if the store's surveillance cams zoom in on your ID as you hand it over?). But several orders of magnitude less intrusive and scary than uploading your driver's license to random websites to read some forum posts.

Everyone seems to be going toward the latter age verification methods right now. Assuming there's no stopping this age verification train, we can try to limit the damage.
