"Be yourself", personally I think children will say what they want to actually say online, not being embarrassed by possible economic differences playing out in their lives.

Parents will be happier not having children not commute in modern society, having to use questionable school facilities, classrooms filled to capacity.

Yes, I think it is worth expanding online teaching due to many factors, you can guide young minds you cannot make them learn. The same questioning minds will be more at ease to ask questions without reproach.
