They both use force. Putting heavily toxic, hard-to-remove substances into tap water -- as additives rather than as "necessary" treatments -- is, I would hope, an action considered aggressive and highly unethical to many people. Consider the degree to which people are now dependent on municipal water and the degree to which water is crucial to sustain life. I would call poisoning a water supply a form of force. It's physical and economic taxation, mostly hurting poor people (who can't afford proper filtration). And it's to the detriment of an entire food chain. Under the new health insurance law, the penalty for not buying health insurance is a fine. I forget the yearly amount: $500-1000 (depending)? Yes, that's a form of force. The amount of the fine and who it impacts is the amount of force. It's economic taxation. It also further opens up a slippery slope in the ability for such forms of force to be used increasingly in other aspects of government and society. That's another topic. Both propositions are easily argued as forms of force. They could easily be argued as unjustified compared to other systems and methods. However, for now, I'd argue that contaminating water is a larger form of force.
