Best way of disabling the Region select for addresses in Magento

Region select is not perfect in Magento. For example, for UK, there are missing counties, probably due how official they are or maybe just because Magento didn’t take the correct database.

One way or another, region field is not considered one of the required fields for most sellers when integrating orders on their ERP.

What is the best and cleanest way for disabling this select box? From my point of view, this is the best way:

Launch this mysql query on your database:

TRUNCATE TABLE directory_country_region;

• You don’t need code changes
• You can easily recover this table
• This will affect throught all the web. No more select menus for region.

If you’re not convinced, you might check other options.
