Blacklists takes in account hystory of coins, so if a parent address is blacklisted by some services, if you have coins coming from the blacklist, you won't be able to buy your starbuck.
Because you say so? I don't agree. Blacklists take into account only specific addresses. Taking into account the history of the coins is simply retarded and will be done only by those that do not understand Bitcoin.
Just my 2c about blacklists: As soon as they are a reality bitcoin will be dead.
Money needs to be fungible, everything else is nonsense.
You are wrong. We already have blacklists when it comes to businesses and to people that made financials schemes. Every time someone opens a bank account they are verified in banks own black lists and banks share their black list database with other banks.
If you own a company and do maintain a business relation with another company that does tax evasion or does anything illegal you are not punished in any way. Stop with this blacklist nonsense!
blacklisting people is a different story than blacklisting specific coins.
where you every in a store and heard a cashier saying: no i dont take this coin, please give me another one?
