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.
Have you heard about companies getting bankrupted and their stocks going to zero, do you think those are redeemable. When you compare something you need to have some facts as if these traditional investments levitate above the rest 
.You can simply search on google about how many companies went down in the last ten years where investors lost billions. When it comes to BTCitcoin as long as you are holding the private key you are able to redeem the coins.
Regarding the last point. You are not able to redeem Bitcoin, but sell it. Only the issuer of an instrument can redeem it and then the instrument units cease to exist.
