In one of the last TSA threads a few people insisted that requiring a driver's license (also) unduly restricted freedom of travel, totally disregarding that driving is different from flying because you are operating heavy machinery in public.
I think a single DWI should be an instant and permanent revocation. DW-Texting/Facebook should be at least a temporary revocation. Having a computer on your face is the same class of thing. If you're so important that you can risk other persons' lives to save your time you can afford to hire a taxi.
