Sorry if I implied you were making that comparison. The comparison is my own: I do feel that civil disobedience should only be utilized for things of that scale.
For things where the dispute is over efficiency or cleaning out obsolete laws or correcting over/under-regulation, actual political involvement applies. Campaign vigorously, support and send candidates who feel passionately about your cause, withhold support from those who do not. Hold rallies, organize protests. Be involved.
But disobeying laws that were enacted via legal means and do not violate human rights crosses a line.
Imagine you're upset because your ISP charges massive prices and their quality of service is terrible (like this would ever happen). Contacting their support, reaching out to their corporate office, blogging about their poor service, and taking them to court over broken SLAs are all valid things to do. Refusing to pay your bill because the service is subpar is not.
It's not a perfect analogy, but hopefully it does a better job describing why I draw the line where I do.
