The linked video explains the difference between traditional financial instruments and bitcoin. Traditional are redeemable, while bitcoin is not. Which makes bitcoin equivalent to a losing lottery ticket. Or, similar to a stock of a bankrupt company, a currency of a former county or a casino token of a bankrupt casino.
Just from your poor grasp of how Bitcoin works, it is definitely not even worth checking out the video. Bitcoin at it's heart is a currency, it is a currency whereby one unit is currently worth around 50,000 dollars when converted via an exchange or peer to peer transaction. You might not like that fact, there may not be much logic behind why so many people put such a high value on this particular currency, but it is the present reality that we live in. Currency is just a store of value. As we see with El Salvador, who have made it legal tender (AKA redeemable) what you have said is untrue and the pace is going against you every day. It feels like you either sold out too early or are just jealous that you missed out on the huge gains it has made since inception.
This topic has nothing to do with how Bitcoin works. Instead, it simply states two fact. First, the number that your wallet application reads from the digital media is non-redeemable. Second, numbers on losing lottery tickets are also non-redeemable. The same as numbers on paper stock or bond certificates of bankrupt companies and corporations. The same as numbers on metal/paper coins/banknotes of former countries. Snd the same as numbers on plastic tokens of bankrupt casinos. Which makes your bitcoins equivalent to the said things. And that paying $50K or even a dime for bitcoin is silly. That's all what this topic is about.
When someone states the fact that a particular car is engineless, it's pretty ridiculous to respond by saying: "you don't know how car works".
