I'm sure, but it wouldn't actually be a problem - because a necessary first step is to legalise the process of establishing a separate world society. As in, the current society would have to "greenlight" the new society - primarily based on mutual gain and feasible co-existence.

If you want to go kill volunteers because they want something else, that's your business. But you would naturally suffer the consequences of being a murderer in your current society.

This new society would suffer an endless stream of ignorant fanatics and violent offenders who have a problem using their brain for the good of posterity. That much is a given.

Education about the short-term and long-term consequences will naturally be available - but there will always be people unwilling to listen before acting.
