I'm no doctor, but isn't that precisely how the Measles spreads?

Got a source for that besides a single MD you talked to? Sounds like they haven't done studies on COVID-19 at this point, but other varieties of Coronavirus can easily stick around for hours on a hard surface.

It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems to behave like other coronaviruses. Studies suggest that coronaviruses (including preliminary information on the COVID-19 virus) may persist on surfaces for a few hours or up to several days. This may vary under different conditions (e.g. type of surface, temperature or humidity of the environment).

My understanding is that there's a large number of people who still technically have jobs to return to but are not going in and getting paid right now. They're ineligible for unemployment and having to decide between taking unemployment now or having a job to return to once this passes. This also helps address companies that don't have a sick leave policy. Beefed up unemployment is part of the bill as well.
