That's a terrible premise. Why are you assuming that this flow exists and that billions of people are failing individually rather than the simpler one this flow not existing?
One reason: Whenever I've made the case personally to friends/family, people who are smart but not interested in messing around with tech, I am usually met with a giant shoulder shrug. Or perhaps, in a best case scenario, "Yeah that doesn't sound great, but there's no way I'm installing X to deal with it".
We can always say the case hasn't been made well enough, and maybe it hasn't it, but at what point do you just start believing people?
