It might be more effective, but it's unclear: I don't know of any strategy that's likely to actually help significantly in rolling back the scope of government, by any metric. (I'm not saying there isn't any, only that I don't know what it would be). Note, though, that even people who want the government to do less aren't saying "we'll do nothing", they're saying "we want to choose which things to do ourselves". No one needs a law or regulation to spend their own money, it's only required when you want someone else's money spent without having to convince them they should.
