What are the qualities of a country that might make it more or less likely to freely allow Bitcoins or crypto-currencies? As some examples which seem logical to me, but should only be taken as examples:

A government that is susceptible to commercial lobbying is probably more likely to be pressured by banks to disallow competition with their services.

Governments that have a corruption problem might also be quietly bribed to legislate against a currency that competes with the official one.

Countries that support open source software might tend to have a "for the good of the community attitude" that matches the philosophy of Bitcoins.

For this question, it's probably important to provide references/examples (such as information about who is trying to stop use of bitcoins and why). 

I see the need to ask this question to help provide a foundation for this one: Is there a list of countries that are not likely to persecute bitcoin businesses?
I believe the Swedish government would be less likely to crack down on Bitcoins. I believe they have a political party called the "Pirate Party", which as far as I know, got elected as a reaction to the crackdown on Pirate Bay. I would love for someone to comment, in order to confirm this.
