That kind of attitude towards consumption sickens me! "This piano needs tuning. We should just throw it out and get another."
I get what you're saying, but you sound like someone who has never tried to give away an old piano (especially a shitty old piano). It's usually not "let's throw this out and get another," often more like, "I don't want this piano (that was maybe here when I moved in because the last owners didn't want to move it, because moving pianos is hard) cluttering up my house anymore, and no one will take it away for free."
I remember when we tried to get rid of my first childhood piano (it was a freebie from a relative and we bought a nicer-sounding and -looking one for a few hundred bucks). We kept both pianos for years because no one would take the old one. People would come and look at it and then complain that it wasn't in good enough shape or that it would be too hard to get it out of the house. I'm glad Sun Hat's mom's piano has found someone who wants it!
