To your last point about a live online teacher, I think it would also just be really frustrating for the teacher to be in that position. Debugging code can be difficult at times, and to do so online where you can't just be with the student in person makes it even harder. To your broader point though, I think that resources like StackOverflow, and even some smaller communities (e.g. subreddits) are a great way to supplement online courses (by getting questions answered/dealing with roadblocks). The only issue is response time (a dedicated instructor who was with you in person could ideally resolve it quickly whereas some SO answers can take days, weeks, or even longer, depending on how obscure/unclear it is). I agree though - programming after all is like playing with infinitely many legos; it can be overwhelming but ultimately you need to just get your hands dirty and fiddle... otherwise you won't learn correctly...
