Say's Law of Supply & Demand is a good fit here. This is a solid truth. I got caught with a laugh at the beginning of this post because of your wife's comment "no one would know what it was anyway" BWahHAHAHaa!!! Probably true. We had a motorhome about a year and a half ago. It had a bunch of old wallet keys in it from when I was discovering crypto (none of them containing much value). I imagined the puzzled look on the faces of those who obtained them. LOL.
I went on to be delighted with the rest of your post and its honesty. Thanks for sharing. :)
