In comparison, a central master database with local cache can resolve conflicts between individual records.

That sentence tells me that you either don’t understand or consciously ignore the purpose of Anubis. It’s not to punish the scrapers, or to block access to the website’s content. It is to reduce the load on the web server when it is flooded by scraper requests. Bots running headless Chrome can easily solve the challenge, but every second a client is working on the challenge is a second that the web server doesn’t have to waste CPU cycles on serving clankers.

POW is an inconvenience to users. The flood of scrapers is an existential threat to independent websites. And there is a simple fact that you conveniently ignored: it fucking works.
