I can hardly believe no one has addressed the cost difference between soap and water vs alcohol. Beyond costs of production, there is an enormous difference is the number of cleanings one gets out of soap vs alcohol. Logistical and storage costs etc.

Cost differences between the two materials are the main driver in soaps popularity.
