Wouldn't these actions trigger the creation of a shadow market for paid transactions?
Some pools will fight and block addresses, while other pools will add transactions from prohibited addresses to their blocks for money.
As long as mining is decentralized, small government mining pools will not be able to block transactions on the bitcoin network.
All written below is just an assumption and it's purpose is discussion!
First of all let's just imagine that rejecting transactions from "black" addresses will become a global trend that have just begun.
Initially big countries (USA, China) will compel pools that are under their juristdictions to exclude "black" transactions accordingly their national blacklists. Because of geopolitical reasons big pools of one country will process transactions form addresses prohibited by other country. For example China will not be care about US SDN and OFAC and will process transactions from these addresses. In this case the circulation of bitcoins will not be more complicated in global scale.
But I think no country will want to process stolen bitcoin or terrorist's bitcoin. That's why it is possible that some day will be created some regulatory international organization, whose purpose will be managing international blacklists of addresses.
If this happens all bitcoin will be splitted to really "black" and "white". In this case, I think, there will not be sense to create "shadow market for paid transactions" because if some miners will process "black" bitcoin it whatever stay "black" and no one will need such bitcoin, because if you receive it, you will have grate problems to send it or change it to fiat.
