1. Not leaving the house won't protect me from Covid-19 if someone else I live with catches it and unknowingly passes it on to me while they're out running essential errands. Not leaving the house while living alone isn't an option unless I happen a stockpile of food and other essentials, or if I don't and want to risk starvation.
2. I don't start "lashing out in anger" until some would-be debater with a superiority complex starts posting comments full of condescension. Maybe you should try being a bit more constructive in your posts?
3. The stay-at-home orders aren't the same thing as house arrest. I'm not completely sure how much the different stay-at-home orders vary from state to state (or county or municipality level), but the ones I have looked at seem to have more or less the same pattern: to stay at home unless a) going to work to provide essential infrastructure services (food, agriculture, healthcare, financial, energy, communications, transportation, law enforcement, waste management, manufacturing, etc.), b) going to run essential errands (picking up groceries, ordering curbside and take-out from restaurants, getting healthcare services for themselves, a family member or a pet, engaging in religious services provided certain social distance guidelines are observed, getting gas for automobiles, going to the bank, etc.), and c) engaging in outdoor recreational activities such as walking, running or hiking, again, while bearing in mind the social distancing guidelines (staying 6 feet away, and avoiding gathering in groups).
House arrest is a punitive measure applied on an individual basis to criminals. The details vary, but it's generally understood that a person under house arrest is not allowed to leave their residence except for employment (usually this will require some verification of schedule), or for medical reasons, until the probationary period ends, and such a person is put under some form of surveillance (usually an ankle bracelet).
Stay-at-home orders and house arrest are not the same thing.
