It seems that people think BitCoins could be effectively shutdown by the government so there are no advantages to decentralization & anonymity. If we look back at all of the attempted non-national currencies such as the Liberty Dollar they are shutdown because they are centralized. The Liberty Dollar was shutdown because the central minting establishment was shutdown, not because they caught every person using Liberty Dollars. If you look at the various attempts at digital currencies it’s the same thing. The government goes after the central companies that handle the goods. They go after the “banks”, the “mints”, etc.
BitCoin doesn’t have any “head to cut off”. The government can’t stop the production, use, or spread of BitCoins short of shutting down the internet. As long as people can communicate over the internet then people can use BitCoins.
If you wanted to live off the grid and hide from government taxation right now how would you do it? My guess is living on cash. You can buy all necessary goods/services with cash and most luxury goods with cash as well. The government, in it’s current state, can’t effectively monitor the movements of every human in their country so they rely on reporting by banks, employers and individuals to collect taxes.
Sure, Google, Microsoft, Walmart, etc. would likely report their transactions to the IRS and pay their taxes but the individuals in society can effectively do all their transactions in “cash”, even online. The point isn’t that no one would pay taxes but rather that it would be a whole lot easier to avoid taxes, just like it is trivial to avoid taxes if you do all your transactions in cash.
As a small business owner I could run an online business in BitCoins and not report any of it to the IRS and likely get away with it. I wouldn’t even have to tell the IRS I exist, unlike the current system where my bank tells them I exist. I would have to pay a premium on things like my rent and such in order to avoid notice (it’s more expensive to rent in cash than with a credit history) but if I chose I could easily go entirely off the grid in a BitCoin economy without being required to do all my transactions in person.
The last point in favor of BitCoin is that we don’t live in a libertarian world. We live in a statist world. Currently the government shuts down any alternative currency it can. As established above they cannot do this with BitCoins (no head to cut off) so they instead would likely try to tax it. Even if they could effectively tax it through something such as VAT where the taxes are all reported by big companies rather than by individuals it still has the major advantage over the current system in it’s inherant fixed and limited inflationary system.
If BitCoins became a major currency in the market at least there would be a fixed money supply that the government was not in control of. People could use BitCoins without fear of their value suddenly dropping because someone decided it was a good idea to print 50% more of it. This fact alone makes BitCoin advantageous to any of the current fiat moneys of the world, it is not and cannot be controlled by the government.
