Maybe not at the beginning of the pandemic because of all the unknowns. Over the summer though? Yes. We know how the disease works. If we can keep grocery stores open I'm sure you can put up plastic barriers & enforce mask wearing in government offices. The DMV is open today (as other other government offices that can't work remotely).

Again, I'm not saying this is a perfect system, but it should be sufficient to significantly cut down fraud. If you want a system that scales better, you have to have a reliable national ID system but Americans historically have been very loathe on a functional version, instead using social security numbers for that which fail on many many fronts.
