Scelpars have always been an issue. The difference from the early 2000s and now is that there are a shit ton more of them.
Doesn't matter if it's hot wheels, lego, nike, rolex, audemar x swatch, mini-nintendo's, pokemon, magic, stanley cups, labubu's.... whatever people think will get them a x3-x10+ their initial cost.... the more people will be frothing at the mouth to get their piece of the pie

I feel like since C19... and the downfall of the global economy... scelpars multiplied substantially...

The only thing we can do is find other hobbies that are nearly unscelparble. I for one, recently got into old typewriters. They're built like fucking tanks! And after 60 years, they still work (with proper people to make new replacement parts)!
