This is the very basis of yard sales and antiquing.
It's how I get a 1999 BMW Z3 with 20K miles back in 2008 for $5K bundled with a Mac Cube and several $K of other goodies from a widow of a former Apple employee. She just wanted it gone. I didn't even "hardball" her - I gave her what she asked for all of it!
I got a vast stamp and coin collection from my father: my sibs who live within 50 miles of my mother wanted nothing to do with it; she's getting on and needed to deal with it - I was willing to come across the country to take it all. Now I have quite a collection of both valuable stamps and a ton of gold and silver.
It's how you get cheap Ham radio gear, machine tools and furniture also - estate sales.
The article is ignorant of all of this apparently. Never had anyone close to them actually die perhaps. The "problem" will solve itself and no one will notice it ever was a problem!
