We (in the US, at least) are paying able bodied people not to work, precisely in order to have them not work. The policy being that it is better for the entire society if all the laid-off service economy people (retail, hospitality, entertainment, restaurants, etc.) stay home. If we did not pay them, they would find other work, which would require them to leave home. Which would be counter to the public health policies. Staying home is the _point_ of the policy, not a side-effect.
