No one will *pay* (=give money to the host) for lost revenue due to deactivation or cancellations.
The purpose of travel insurance is mainly to cover the traveler's additional expenses (for accommodations, meals, medical, extra transportation, difference in airfare due to change) due to unforeseen events that happen while traveling. It doesn't cover loss of potential revenue (for the host that the traveler stays with.)
Also, you should note that depending on coverage, a lot of travel insurances no longer include coverage for covid-19 quarantine unless one is diagnosed because it is now considered a "foreseeable" event.
