The question was “why can’t you automate it?”.

[koolba]

Automate doesn’t have to mean a machine is handling it. It means you don’t have to handle it. Human automation is a valid tool, in particular for things like housework.

[robotresearcher]

Automate usually does mean to use machinery.

I open a car factory. It is fully automated.

See?

Besides, the original question is totally boring if you allow human automation. Of course I can hire someone to do labour. No one needs that explained to them.
