Millions of sets in use today dont have that, and do run with live

I just gave away a 10 year old JVC and that had an isolated chassis as
does my new Sony and the two 5 year old small bedroom sets.

I'd agree that all the quality makes I've played with have been fully
isolated.

BTW they all
had/have headphone sockets too.

Most quality makes do - and also AV connections, so they'd have to have an
isolated chassis in practice.

How could they run modern electronics without a transformer of some kind?

If there were no external connections, you could use a form of auto
transformer which is marginally cheaper?
