People have plenty of natural incentives to leave the house ("reasonable time" is a sign of your own biases, but no doubt leaving the house is healthy regardless). The reason people don't do so is because there are strong economic disincentives to do so. This is not just obvious conscious disincentives like "I don't have time because I need to earn money online" & "I will have to pay for X, Y, Z in the city if I go out" but also much deeper more complex systematic disincentives like "I am chronically ill due to years of economically-linked stress and burnout" & "I feel depressed due to economically-linked lifelong trauma"

Healthy people don't need employers to incentivise them to leave the house. And unhealthy people don't need work, they need support.
