based on the Victory unit, but prices are around $900. They are sold out, even if I was going to pay that much.
I see list prices more like $600 ($599), but as you say, they are sold out.
>> surfaces, and seems to go against the hand washing advice.
I don't think the one implies the other. It's all a probability game and there are many things that can infect you from your hands aside from SARS-COV-2.
Most of the infectious disease specialists I have been reading all through the pandemic have been saying roughly what I said above regarding surfaces. It is a theoretical, but difficult, pathway and the main source of infection is breathing exhaled droplets or aerosols from an infected person over an extended period of time (that is, it's almost impossible to get from an infected runner who passes you on a trail, but riding around in the car with an infected passenger and the windows up would not be a good idea).
If you have the mind space to pay attention to everything, then yes, watch those surfaces. But if obsessing on surfaces is decreasing even a bit the mental space you have and therefore your vigilance with respect to aerosols, that's a bad trade in my opinion and that was more Osterholm's point, rather than saying not to wash your hands.
Rather, Osterholm says you should absolutely wash your hands and that personally he does frequently, but he does so mostly because of all the diseases that have always used that pathway effectively. I suspect given his work, back in 2019 he was washing his hands a lot more than average, and he has not really changed practice. But he said specifically, he's not concerned with touching doorknobs, opening mail, bringing groceries into his house. Keep your eye on the airborne pathways.
The Osterholm interview is quite good. I strongly recommend giving it a listen.

None of this is to say you should be cavalier when you venture into the outside world. Washing your hands, avoiding touching your face, being diligent about physical distancing, wearing masks in public, and disinfecting communal surfaces — all these things likely reduce transmission risk, and we should keep doing them, Rasmussen said.

The focus on aerosols and droplets came up over and over and over with the county public health officials.
If you can do seven things, then, sure, disinfect every surface and wear a hazmat suit. I wore a full P100 cartridge mask to go strip the beds because I own two that are right at hand. Stripping beds is going to kick stuff into the air, so why not be safe if it doesn't take much more effort?
Obviously, the level of care you take has a lot to do with your risk tolerance and your objective risk factors. If I were 86 years old with some respiratory issues (my father-in-law), I would be much more careful.
