Should we also have a ban on all sports memorabilia then? It’s a gamble for me to go to my local team and have the players sign things and then at some point in the future it could be worth a ton of money?
Would this conversation be any different if they sold the cards for what they think the expected value is? Then you’d have people complaining about how they’re charging hundreds for a card and that’s not fair because little Timmy can’t afford it.
Edit: those tumblers that people drink out of have “rarer” colors and designs, better ban those two because of gambling.
