I am also glad that someone has the luxury of just buying whatever couch suits their decor - but you’re being awfully flippant by presumption that that’s a normal state of affairs.
By and large people buy what they can afford, not what they fancy, especially for something big like diet other.
When I bought a couch, I had a budget. What I didn't do was walk into the store and ask myself how this couch is going to pay for the square footage it occupies. It won't. It can't, that's not the point of a couch.
By the logic in the top comment, nobody should own a couch because it doesn't generate money that would offset the cost of the space it occupies. That's my issue with the top comment.
Nowhere in the OP is there a suggestion that they are doing it with the intention of saving (or earning) money. Nobody, no matter what their means, buys a couch because they think it will behoove them financially to do so.
OP made an aquaponics thing because they wanted to. I bought a couch to sit on it. God forbid.
And on that note, buying something cost-optimized to your space is itself a mark of privilege. My first couch was the nearest free one to my home, since I didn't have a car. It was much too big for the space I put it in. But it's what I could afford, which was nothing.
It seems that there's someone in New York eluding suffering by messing around with aquaponics. Good for them.
When you buy a couch, are you thinking "will this couch offset the value of the square footage it occupies" or "will this couch be comfortable and match my décor?"
I'm glad someone is doing something fun in their home.
