Anyway, my question: I think I understand the legal distinction between
licensing and certification, but what are the *practical* consequences
to me as a pilot in that distinction? In other words, how would my life
as a pilot be different if the US licensed pilots rather than certifying
them?

Probably none...but if the issuing authority calls a piece of paper or
plastic a "certificate", why would anyone call it something else?......
ignorance???
