You are missing the whole point. The OP is mentioning how people are so used to using github, that they are so oblivion on using git offline
Tons of people who DO use git cli don't know git init. Their whole life was create a project on github and clone it. Anyway initting new project isn't the most "basic" thing with git, it is used less than .01% of total git commands
if you combine the above easily MOST people have no idea about git init
