It's a little of column A, little of column B, but in a mixed way. A lot of doctor visits for basic health issues are ones that can be dealt with over a phone or video call. Routine stuff like updating your medicines, changing dosages, showing a bruise or dealing with a mild fever don't require you to be physically present at the doctor's office. Having to deal with insurance, scheduling, waiting times, driving to the doctor's office in the middle of the workday are unnecessary for a large proportion of the sorts of day-to-day issues people deal with.

Telemedicine isn't a panacea, but in a system with major constraints on doctor bandwidth and where in-person visits are very expensive, it's extremely helpful. And yeah, a lot of that is because so often the solution is as you said -- get more sleep, eat better, maybe work out a little, reduce your stress. I'd much rather have a quick 15 minute call to be told that, instead of having to take several hours off work to go visit the doctor in person.
