No shit, you leave a huge mess for the people you love the most to clean up. And it's worse than that, because it's very emotional for them to handle. There's a strong drive to become a hoarder when you're looking at things that someone you lobed dearly valued highly and your option are to toss it or keep it forever.

Don't collect things that don't make your family wealthier, and if you must, try to teach at least one of your children to enjoy your collection so that at least someone is keeping it because they want to have it.
