I appreciate your post but it is a bit missing the point, you kind of over analyzed this. What is usually meant with deep bags is people who invested in yet another revolutionary innovative bullshit coin or token that was meant to change the world, but in the end it was just as useless as many of them. A simple tell is when people exaggerate the benefits of a coin or token but dismiss any legit criticism of it. An example would be Ethereum bagholders. They will dismiss any concerns that it is quite centralized, both in governance and on blockchain terms.
