I live in a 600sq ft 2-bedroom apartment with my wife, and we cook nearly every meal at home, we rarely go out to bars, or spend much money in the city.
But we have 6-7 cute cafes within a 5 minute walk, so we stop in for a coffee now and then. We have a big park that we can picnic in, three blocks away. There are a ton of fun things to do for cheap or free nearby.
We don’t need a ton of space at home because our city provides us a lot of happiness.
If you can walk to handle all of your basic needs, then you don’t need to have so much at home, is the point that the GP was making.
For example, we keep much less food at home in Europe than we used to in the US, because I can just drop by the veggie stand or mini-grocery on my walk/bike home from work and get a fresh version of whatever I want to cook that night.
We don’t need a beer fridge because there is a beer store selling cold beer cans within a block of us, and with way more selection.
