The influence these interests and agendas wield is mistaken by some as an inherent characteristic in the concept of government itself. This is an error, and not at all useful.
This is not an error. Government, by definition, will attract the worst elements of society who will use its unique powers on their interest. An industry cannot use guns itself to rule out competitors, but it can bribe government to pass laws which end up doing the same thing.
Just think in terms of costs and incentives. Put it in numbers to make it simpler. For example, imagine there is some particular law which, if approved, would cost every 300 million US citizens the equivalent of $1 each. On the other hand, this same law would benefit a small group of 100 individuals making them earn the equivalent of $2 million each.
Net = 100*2.000.000 - 300.000.000*1 = -100.000.000
The entire society loses the equivalent of $100 million. It's clearly a "bad law", even if we just get the net results, ignoring the unethical aspects of income redistribution. And it's clearly a law that inevitably will be approved.
That is simply because, if you're among those who would lose $1, you won't even bother knowing about such law, not to mention organize with others in order to prevent it from being approved. Those in loss will not do anything to stop the law, because the costs for doing so would largely exceed the losses they will suffer with the law.
On the other hand, those earning $2 million each would probably be among the ones writing the law, and would even invest more than one million each in lobbying and organization to get such law passed. They will win.
This "overtake by unscrupulous interests" is inevitable, and it is an inherent characteristic of government.
Yes, it's true. Sweden for instance is ruled by a small clique of mink-clad gold-toothed government beaurocrats that rule by balance-book dictat over vast apathetic swarthes of a population that languishes uneducated and diseased in the dark and sprawling slumps of Stokholm.
Have you ever considered that the problem might be with the kind of governments that are produced by the Market-Liberal tradition? If your political sphere is a mere market-place, you should expect trade. Ironically people who talk like you do tend to want precisely that, unfettered market fundamentalism. That's why things like democracy and socialism is opposed by such people, it would interfere with their profit margins. That's why I'm against libertarianism, I don't want a government that is free to be bought and sold by the highest bidder with the necessary market power.
I want a government that is kept honest by a well-informed enpowered population that demands quality for it's tax-money, a government restricted to spending its taxes on public goods and subsidizing the value of non-commodified human existance. If bitcoin takes off then the shaddowy handlers of payment companies wouldn't think they get to pull levers in the background to stiffle innovation at the expense of everyone else like this.
Market-liberalism and libertarianism mean oligopolies and monopolies get to get together and game the system to their own benefit with precisely those Austrian calculations you posted. This is precisely what communism, democracy, anarchy and socialism etc are strategies to oppose. People taking government seriously as a common-good, engaging and demanding it to be used for common-goods is what crashes your Austrian School calculation. Political decision is not a market and if it behaves like one then you should change the architecture. I'm no communist or socialist or anarchist (I'm social democrat) but I am against being ruled by private dynasties and corporations of various kinds lording it over politically unconcious and unempowered populations that vehemently oppose their own interests.
Anyway all that aside, this particular payment-system game has already been outmanouvered by the coin, and that's very satisfying. It's almost Thai-Chi... use the energy of their attack against them. Unjust legislation like this just goes to help the bitcoin value.
It's a classic example of bitcoins democratization of money dissempowering price-makers and causing their basis to buy government for their own ends to dissapear. An elegant solution in my opinion.
