I think this just crowdsources the server’s load. Servers will certainly have to handle fewer requests thanks to PoW, at the expense of clients’s CPU time. The

  >The upside is that the server does not go down, so at least some users will be able to access the website, compared to zero users Yes but the price is very important. Imagine you visit a country, and paid car rides, (i.e. taxis) cost one thousand dollars per hour. It might be the best ride you have ever taken, but it excludes 99.999% of the users due to price. The problem is, it is impossible to figure out, how much computation is a cheap computation without first relying on a marketplace of computation and discover the price that way. The blockchain technology serves exactly that purpose. The producers of PoW, the miners, sell their PoW to consumers. Consumers bargain the price, by using it less when it's expensive, and more when it's cheap. The blockchain logic states that: "Requiring users to give proof of burnt energy -> good idea" "Requiring users to burn energy themselves and then give proof of burnt energy -> terrible idea"
