>>59309390I believe that it is less that it is difficult and more that people do not put forth the effort.
When I write sentences with this sort of prose, or even really just use simple grammar, it generally demarcates me as a "tryhard."
Most people simply do not care to use periods or even necessarily commas as a run-on sentence is not considered that much of a grammatical faux pas in a "conversation" which is what Youtube Chat essentially is.
TL;DR - people don't want to come off as pretentious and pressing , or . is extra effort that most people can't be bothered to exert.
