The biggest problem I see with the proposed solutions at the bottom is that the author arrives on the two node-based solutions as the preferred path forward. The reason Wordpress has become so successful over the years is that even the least expensive hosting provider has mod_php installed and you merely have to drop your installation files on the server via FTP. This is easy enough for many less technical people to accomplish. Node, ruby, and the like typically require more advanced and expensive hosting solutions, in my experience.
Of course I haven't used any of these cheap hosting solutions or setup a Wordpress site in a couple years so I might be out of date on the state of things.
