Economic majority is not applicable for PoW coins. Hashing power is what decides the fate of bitcoin, not the people who holds a shitton of it.
Hash power merely decides which valid chain is the best chain. Essentially, their only power is to decide which transactions get confirmed, and in which order. They can't just arbitrarily change consensus rules like the the total bitcoin supply. If they break consensus rules like that, the economic majority -- exchanges, services, economically relevant users -- would just ignore their chain.
