Not to raise unnecessary skepticism, but have proof-of-work ever been
successfully deployed for anything in the real world (besides for
proof-of-work per se — i.e., Bitcoin)?

Did you try to estimate how much CPU work would get one a token once
such system is deployed full-scale, with spammers (possibly with
botnets) competing for resources? E.g., you can get a rule-of-thumb
estimate by putting some dollar value on a token, and looking at the
generic-CPU work required for an equivalent Bitcoin amount.

Perhaps captchas might look more appealing after that.
