Well then, write a letter to Congress and get them to start their own freaking block chain...
It is likely that current authorities will adopt attributes of bitcoin in one form or another given bitcoin removes the mint and current transaction processing system, they also have strong motives like preserving current wealth of powerful figures.
You are defining what a currency is: an object that by mutual agreement everybody starts using as means of exchange. It is only later that governments come and create a monopoly.
By governments you/I mean enforcing entity. And historically it has been the enforcing entity that existed first, then the currency. Today's currency systems, there is no need for a mutual agreement at the point of transaction, the exchange of fiat will be recognized by the state. The mutual agreement manifests itself when citizens vote and their faith in the state, that their politicians will make sure that the monetary authorities adhere the rules outlined and preserve the value of fiat, this I believe is the fundamental issue is the failure of adherence, of-course it has wider implications for other aspects of society.
Its quite sad that you think that only through government can things work, when reality shows us that its the other way around.
Which currency system are you refering to? I am unaware of any currency system throughout history that has existed without a 'physical authority/backing'
Imagine the situation in one or two years, where more and more business are starting to accept bitcoins. Now another group starts a new chain, and then another one, so we have three e-currencies. The problem for the two new ones is that nobody is accepting them, the companies only accept bitcoins. It would be difficult for the new currencies to be accepted by the business because no one uses them, and no one uses them because no business use them. So people will continue to use the original bitcoins and not the other currencies.
Like you say let's imagine;
that no one will care about the fact 25% of bitcoins are already minted. this is a separate issue regarding minting implementation, not relevant here. that current entities of power will just allow a simple transfer of power to bitcoin holders
that no one will start another crypto-currency, that is potentially recognized and backed by a physical entity
that current states will adjust their currency systems to incorporate features of bitcoin, thereby providing physical backing on top.
Do you just mean that fiat currencies are backed by a government that will enforce contracts based on them? If so, I think that is a somewhat weak assertion. Courts in the US are generally recognized as worthless for settling contract disputes, and are only used as a last resort when large sums are at stake. Private enforcement (ie the mob) and third-party transaction insurance (eg paypal) are arguably better models.
Yes, I mean physical enforcement. A system of control/belief that users will adhere to and implement, it really doesn't matter what form it takes as long as it has properties I've outlined prior.
Or do you mean to argue the absolute extreme case -- that any viable currency must enjoy absolute monopoly as a store of current value, and this monopoly must be maintained by force?
Yes, something along these lines. Lets say only one bitcoin system could exist in the universe, then probability of bitcoin working would increase, although whoever has control of the most cpu power may control the system(this maybe a weak assertion as I'm not up with the inner workings of bitcoin). Gold for example has a small pre-determined supply, hence why it is used as backing.
Are you arguing that high taxes are good for an economy?
No thats not what I'm arguing although I'm Aussie and I would say yes, based on outcomes achieved in Scandinavia, thats an entirely different discussion
.
I think also that if people are going to assume that bitcoin will work, then naturally you will be competing against other current currency systems. So the expectation is that bitcoin will replace a significant proportion of modern day currency. By extension there will be a massive shift in global power, and no one seems to think that is going to be issue; given that I believe that it will be relatively simple to start a new crypto-currency. This doesn't even take into account an enforcing entity.
