In general, if you want to do something you more often than not have to compete nation or even worldwide. It makes markets more efficient in the minds of some economists, but makes creating or finding valuable things fucking exhausting.
What people are really complaining about is that the hobbies of thrifting and collecting have been overrun by professionals. That’s going to suck for any hobby that involves buying and selling.
Then somebody posted about it on fucking Facebook. Now ragged out used tools sell for more than new price, and the buyers are always from cities 5+ hours away here to take advantage of the low prices since us country bumpkins don't know any better.
Used tools were a nice way for young people to get started in the hobby. Now they're too expensive for that to be realistic.
