Mike is calling for a discussion about the issue. He's not suggesting it be implemented in Bitcoin.

The fact is, Bitcoin's design fundamentally makes redlisting possible. No changes in Bitcoin are needed to start redlisting coins. Anyone can do it. All that is needed is a server (or a p2p network) that stores a list of transactions that are redlisted and allows people to make queries to the database.

This can be done right now. The biggest obstacle for redlisting currently is the difficulty in convincing people to care about the fact that you're redlisting coins. A government has a way to make people care about it. It's almost guaranteed that some government will try it.

The only way to prevent this from happening is to get involved in politics and convince the decision makers to not do it. If this fails, the worst case scenario is that this is done in a way that makes use of bitcoin in the country involved very impractical.

If you don't like this scenario. Here's what to do:

• Keep an eye on the political scene in your country to make sure you don't miss movements towards this scenario
• If you see any, do what you can to oppose them
• Think up technical ways to combat usefulness of redlisting
• Stop trying to silence people calling for discussion. That will make the problem worse.
