Ok, I'll give you one huge example why it doesn't work with any public asset: Bitcoin is a public digital asset that is not considered a security by any standard definition out there. For one, it's truly decentralized, meaning that you can't say that it was issued by any particular person. There's also no investment contract involved, meaning that there's no indication from anyone that you'll generate a return on your bitcoin purchase. Furthermore, bitcoin is not a company, and therefore there is no board of directors or employees with titles like CEO or CFO, which means you can't point to anyone in particular and say you are relying on them to make good decisions to protect your investment. So no matter how you look at it, Bitcoin is not a security. And so in order to move forward into the digital age, a new set of standards needs to be implemented so we can identify which category that each digital asset belongs in for the sake of applying the proper rules and regulations. Some might be securities, some might be commodities, and some may fall into a completely different category altogether.
