Non-service animals, crying and seat kicking children, the sick, the morbidly obese (if you spill over your assigned seat), smokers, people who wear too much cologne/perfume, people who put their feet/knees on the seat in front of them, snorers, stinkers, those allergic to peanuts and all other classes of public irritants should have spots in a comfortable but separate cabin.

This separate but comfortable cabin already exists and is called "a commercial flight", what you are looking for is a "chartered flight".
