Doge shows us that anything has "value" as long as someone is willing to trade something for it be it your time, service or product. Nothing truly has value to it until the point of sale/trade. The USD is not backed by gold anymore so it's a faith system there as well just like Doge.
However to be honest with you right now at this moment it's feeling like 2017 in terms of the amount of shittokens launched and how wildly people are jump from one to the next trying to make millions, the scams going on in defi etc lead me to think we are getting rather close to that Euphoria stage.
