Well since you visited the site there's probably some reason why you want to be there and whether it's advertising revenue to keep the lights on or optimization to know where to focus your efforts, if the majority of the world blocked either program you'd be paying for the privilage of using those sites. It's no different than people who shop the lowest priced store 50 miles from home then complain when the local market closes... cause and effect. Value isn't just about the short term.
Based on your argument about the percentage of people with JS or Analytics disabled there must obviously be at least one other factor that we haven't worked out yet that is causing the Analytics figures to read so low. I have seen instances where Google AdSense reports more visitors to one of my web pages on a given day (by the number of people who were presented with a specific ad block) than Analytics claims was the total number of visitors.
