Consider posing your statement in the reverse: SARS-CoV-2 does not disperse in droplets, and/or is not infectious when not in a droplet. There is no reason to believe either of those things!
It's totally reasonable to assume the virus could separate from a droplet and would remain infectious by itself for enough time to infect someone. This is common in other viruses, and seems to make sense from first principles. Why would virus particles not be able to form aerosols?
You are wrong. Read:

Aerosol transmission is the main vector.
