doesn't make sense , the legalization is done by a central authority and will help bitcoin getting more recognized or adopted, people also want to be controlled it seems...
Who cares if bitcoin is declared legal or not in your country? I'm not using bitcoins because my government said it's OK I'm using it because I can make my own decisions with my own money.
well if it's not legal you can't use it without trouble, it would hinder adoption, and no one will buy it locally for example, altought you can still use it on the web for purchasing stuff abroad, outside of your country
