The only medium through which people could be discouraged from gambling with their funds into memecoins is when the "get profit quick" feature has been removed from memecoins. But so far as they are made to understand that there's a slim chance of making huge profit in the shortest time from it then they would never stop risking their money there, except as you said it, only when they might have lost way more then they can stomach and that's when they start avoiding it but by then they have lost funds they could have used to start with real asset that has sure potential for a ROI no matter how small the profit could be.
