From reading the text, it seems like those folk wishing they had been alive in 1776. (The year of the Declaration of Independence of the United States from Great Britain, which the Ethereum Classic document appears to be modeled after.) This document does remind me of reading "A gentle introduction to Unqualified Reservations (part 2)" (https://unqualified-reservations.blogspot.com/2009/01/gentle...), which includes this passage by way of a set-up:

    Anyway. Our point is the conflict you call
    the American Revolution. For a quick self-
    test, ask yourself how close you are to
    agreeing with the following statement.
    (You're not expected to take this on faith
    - we will demonstrate it quite thoroughly.)

    Everything I know about the American
    Revolution is bullshit.

The thinking behind the Ethereum Classic Declaration of Independence seems to stems from a reading of Mencius Moldbug, from which you may draw your own conclusions.
