I mean, yeah, obviously nobody wants either, but

> Bot prevention is not my problem as a user anyway

It isn't until it is. Today already one needs to

- "hold this button for 5 seconds to access this website" (and if you let go in between it offers the same captcha but will deny access until you reload the page and do what they ask), e.g. phys.org article I accessed iirc from HN

- Select all mountains or whatever, many forms on many many websites

- Rotate this puzzle piece until it fits (Chinese video website where someone linked to from YouTube because the randomly selected Chinese recipient of a gift posted their reaction there)

- Add up the dice from these 15 pictures and select the matching die (github registration)

- "Your IP address doesn't have access. Request ID 929cjn289w." various websites

- "Something went wrong" -> open the developer tools -> server says IP address blocked. Retry with a different user agent string succeeds. (German eBay)

- Can access something from popular browsers but not then grab it with curl because they block that user agent (I needed this because my Android "download manager" was broken. Why the browser can't download it by itself like on any other OS, I don't know, but so I need to do downloads with wget/curl/whatever and this is very often blocked by user agent string)

- Verify your phone number to prove you're not a bot (Microsoft, Google, German eBay, Telegram, you name it)

But it's not your issue as a user! :P

More seriously, this is why I'm bringing this up now before the choice is already made, things magically work for the 99% using crypto solutions like proposed in the submission and the freedom to run free software is even more impaired than it already is today (ask anyone who runs a custom ROM or something as heinous as rooted their device but would still like to use payments or get updates for their device like a normal person)
