I'm not sure... I get the sense that eggs of the 1800s were likely a byproduct of having chickens, or barter with someone who had chickens. Yes, some effort went into them, where now it's more likely that the effort goes into work which turns into money which turns into eggs.

But, I've made a choice: I'll pay for eggs at the market rather than have chickens, because I don't want to have to deal with chickensitters when we got on a trip. This is the sort of choice that the person you're replying to is talking about.
