Anyone who has their transactions "banned" by pools will simply pay enticing enough fees to have other miners include their transactions. OP seems to ignore financial incentives when speaking about banning Bitcoin. If there is money to be made, people will route around any regulations. This has been proven over and over again in the history of the world.
A few questions.
If people have to pay high fees to get their transactions confirmed, why would they use Bitcoin rather than some competing form of money transfer?
If the the hashrate of miners including blacklisted transactions shrinks to insignificance vs. those who adhere to the blacklist, surely it doesn't matter how high the fees are? Those transactions could take weeks/months/years to confirm, depending on what percentage of the overall hashrate the adhering farms represent.
Actually they would never confirm, because the 50% hashrate could blacklist the minority hashrate. This hints at franky1's logic error.
50% of whom? The mining businesses that don't want higher fees?
The mining business that doesn't want to be raided by the authorities and have their computers and ASICs farms confiscated.
As long as they are paying their taxes and bills, why would any authority do this?
For not complying with an AML (Anti-Money Laundering) regulation requiring them to blacklist transactions and mining pools which don't require identity for all transactions, e.g. all transactions must originate from Peter Thiel's Coinbase, BitPay, Paypal, Facebook, etc.. where the user has provided the necessary KYC (Know Your Customer) documentation.
My gosh it is only 13 years since 9/11 and all the Patriot Act crap which has spread to every country under USA pressure ("you are either with us or against us", POTUS Bush), and you guys are still clueless at the modus operandi for how the powers-that-be are taking control of everything via the terrorism false flag paradigm.
Yeah I forgot about 911. Now I feel fear, uncertainty, and doubt. Don't they make pills for that?
