The second is that hand sanitizer isn't even necessary, soap and water is better, and people paying $7 for a bottle of hand sanitizer are ignorant when they could just buy a bar of soap.
You basically can't get out of an office bathroom without realistically touching several surfaces of questionable cleanliness for a contagious pathogen, for example.
Coronavirus's are a class of viruses well known to be susceptible to deactivation by alcohol exposure [2].

No it doesn't. The study you refer to was one specific virus (influenza-A) that simulated essentially coughing directly onto your hands. Where the virus was encased in large volume of mucus.
That isn't how people use sanitizer. It's for dry contact displacement, and there it is incredibly effective. You should still wash your hands when you can, of course, but these misleading claims aren't helping anything.
How about when you get off the subway and need to grab a quick lunch at small establishment that doesn't have bathrooms?
In NYC, many lunch places have only maybe 4-10 seats at a window or something. The law says they don't need to provide a bathroom, and they usually don't (no space).
Or even if you go to McDonald's or something, there's often a line of like 5 people each taking 10 minutes inside the single bathroom. (Welcome to New York.)
Hand sanitizer is literally the only way many times not to get the virus from your hands into your mouth when eating.
Sanitizer is useful in situations where you can't wash your hands. Like when you get out of the subway system.
On the other hand, putting gloves helps me avoid touching my face, so I'd go for that.
