Yes, because when I'm hosting a server to play Minecraft with a few friends I need redundant power, network, and administration. It's not as if I could just go to Best Buy, buy another stick of RAM, shove it into my decently spec'd desktop, port forward to a self hosted server, and get 99% of my necessary performance for a tenth of the cost (over a year of operation). Plus I don't have to return the RAM to Best Buy after I'm done with it. Because casually hosting a Minecraft server is ALMOST the same thing as hosting a SaaS which needs 5 nines of reliability.
