At the risk of starting a philosopher's jamboree here, I think that Heisenberg way well have been outlining limits to our knowledge, not just limits of our technique. There is much that we can never know about our physical universe. There are limits to our perceptions that are determined by limits in our physical ability to quantify and perceive. We have no knowledge for instance or any ability to understand finer than certain sizes of energy/matter. We have no ability to view these events in vanishingly small increments of time or to understand the way that these vanishingly small particles interact in these vanishingly small universes of energy/matter. Nor do I expect that there are any practical results for us if we did. At the other extreme we have quite the opposite problem. We do not have any way of understanding our universe in time frames beyond our cosmological limitations. Since the current limits see only so many billions of years since the big bang, we are basically separated from any possibility of knowing or certainly interacting with what is beyond the glimmers of our time/space horizon. So to suggest that Heisenberg limits do not necessarily limit our understanding is not necessarily a true statement. We are bounded in our current middle ground of time/space/mass. Beyond the limits of our extremes, both large and small, we have no way of knowing. Heisenberg uncertainly provides us with a useful articulation with some of the problems that are associated with our ability to interact with the physical universe, and thereby substantiate our understanding.
