You're comparing apples to carrots. Not even close.
I've taken 5 classes over the years. Only one was a typical classroom setting with maybe 20 students. The rest were 6-8 students sitting around a table. All were one evening a week maybe 7-9 pm for, I think 8-10 weeks.
The inconvenience of travel and parking and being away from family was minor to say the least. Never once did an instructor fail to show up and since the classes were so small, he would have called all the students to let us know if there was any kind of problem.
Not sure how "sitting around a table" differs from a traditional setting other than the lack of an idividual desk.
As for your personal experience of having an instructor never late,absent or fail to communicate a cancelation, lucky you. I doubt your 4 examples are 100% representative of all commercial class situations.
glad to hear the transportation,travel issues were minimal for you, My experience can not be minimalized due to the rural location and availability of classes offered. or to state it plainly, I'm in an area that is far from these classes offered w/ no public trans. options.
for me , the thought of driving an hour each way for and evening class one night a week for 6-8 weeks is a definate shoe stopper. Particularly after an 8-10 hour work day and oter obligations. Whats more, once a week? how proficient and to what degree of retention could a 2-3 hour once a week course offer?
I've participated in alot of "education" situations offered from different sources from public,private,military . though a wide and varied area of education to include Aviation, forestry management ,electronics,pedorthics,transportation,medical,mil itary related underwater demolition/construction,music,lutherie,wringwainer to name just a few. and have been employed in each area at some point.
I'm stating this to emphasize I have personal experience with many different education methods and find little disadvantage in online education compared to the advantages.
why is it improper to compare vegitables to fruits?
