Governments have nothing to gain from bitcoin. There is no being left behind here.
Established governments are in danger of being pared back, but the benefits are enormous. It's just a shame they're so hard to recognize from within traditional systems.
- Reduction or elimination of expenditure for currency management
- Increased transactional currency stability
- Preservation of purchasing power
- Long-term stability and viability
Outlawing bitcoin is actually quite easy: show examples of drug dealers/pedophiles/terrorists using it (real or not), write a law, pass it, ban bitcoin use by citizens of the country where the government governs. This would automatically prevent that nation's banks from dealing with bitcoin exchanges, thus frustrating most ordinary users' ability to use bitcoin. No need to block actual bitcoin use. Just threaten users with penalties similar to money laundering.
It is impossible to legislate anything out of existence, especially anything making use of advanced technology. What you're describing is a smear campaign, which must be maintained and increased in proportion to the elimination target's growth. Because of this, the resources thrown at a 'problem' can rise to exhaust the ability of a government to manage it; time is
not a factor in any centralised government's favor.
Currency exchanges are currently the weakest link, but that does nothing to stop internal growth in the Bitcoin economy - in fact, it paradoxically hastens the growth of Bitcoin. Increasing disincentives in fiat systems spur users to flee to alternatives. If the fiat restrictions are great enough, users may completely switch to selected alternatives instead of remaining exposed to liabilities in the former.
Enforcement of Bitcoin prohibition is completely laughable. This would be akin to attempting to directly control every cell in your body all the time using conscious thought. Growth in use can by slowed, much like an infection. If a finger is gangrenous, it can be amputated, but would you incarcerate one of your arms by tying it behind your back or losing it altogether? Both arms? A leg?
Bitcoin isn't very useful to most people without free and open ability to transfer money to/from exchanges and the subsequent funds to/from banks. Try to sell 10000 bitcoins for USD$ on the internet without using an exchange to see how difficult it can be.
Not yet, but the transfer to/from banks becomes irrelevant when internal Bitcoin economy growth expands. As payment in BTC is accepted more readily, there is no need for conversion to fiat. This transition is all but guaranteed now.
Familiarity with the operation of precious metals as currencies lays the groundwork for comprehension of Bitcoin. By the end of this decade, prices might be primarily denominated in bitcoins and gold/silver grams instead of fiat; one-world currencies completely different from the totalitarian fears imagined during the 20th century.
