The only way to devalue monopolies is by decreasing the currency supply and the only way to do that is by converting or changing the money supply. Net Neutrality unfortunately at this moment in time is necessary because without it, these monopolies that currently exist will still exist and take full advantage of the power they've gained through government. Yes the free market provides but not when monopolies have total control of an industry and the entirety of that industry is based on government programs.
Unfortunately it is the free market that creates monopolies. As a corporation grows and becomes too wealthy, it just buys smaller corporations that compete with it or prices them out of the market. In a free market (which does not exist) there would be no laws/policies to prevent this from happening.
In a free market over time monopolies are naturally created because there is nothing to stop them. Even in a somewhat free market, as we see in the USA today this can happen via crony capitalism and corporate takeover of the government. Corporations and the wealthy people that own them start either creating or eliminating government laws/policies that interfere with their revenue, by buying/funding/bribing politicians.
Without fiat currency monopolies cannot last long. Unfortunately with central banking an unlimited amount of money can be printed therefore corporations are able to accumulate mass amount of wealth. The math doesn't add up.
Monopolies can still exist in a finite currency system, but yes since more money is not created eventually things get worse quicker. As the wealthy accumulate the majority of the money, they hold more money than they can spend while the majority does not have enough money to survive. Since the banks/gov is unable to create more money the economy collapses and/or a revolution starts. In order for any economy to function the middle class has to have the most amount of money to keep the velocity of money high.
easier to split them in small entities like AT&T of old, or if you think about facebook from what's app and maybe a few other services they provide like splitting the ad business as a single entity and if you are more extremist it's always possible to nationalize it, or worst make it illegal but the money supply has nothing to do with it.
Without an unlimited money supply how would corporations have the ability to accumulate so much wealth?
maybe by providing what the people want to buy better than their competitors? it's not the amount of wealth but the relative share.
