What's ancient? There were continental supply chains in the Bronze Age and earlier.

Of course there were but that's still a weak argument for a 15 hour work week.

For the vast majority of people most of what they needed was around them and it required a lot of work.

There were local supply chains too. For example you could have a guy who just collects wattle all day, or someone who just spins wool all day.

But that doesn't take away that it's still a lot of work. Just to get water is work.
