An additional point to make is the quality of the cholov yisroel milk that you get from the store. Generally, anything you don’t use the first day the bottle is opened becomes sour. Sometimes, the milk is sour even before you open it. So to me that sounds like the situation where cholov yisroel milk is not available still prevails today. (Unless you want to buy a new bottle every day)
Not that this means one should be maikil, just disagreeing with your assertion that cholov yisroel milk is as available as non cholov yisroel milk – even in the Holy “in town” mekoimos.
