If you can get that government plan, great. The point that the author is making, is that in the absence of any such plan, market mechanisms would have allowed many of the people with regards to whom it is a collective benefit for us all if they have received the vaccine -- first responders, people who have jobs that require them to travel or be in public, and people who want to party -- to actually be able to get it. The free market doesn't always optimize to what is best, but the author makes a reasonable argument that in this case it would. You don't seem to disagree with their analysis, just markets in general -- and that's a politicized, unhelpful approach.
