> you thereby increase its momentum You don't increase its momentum. You increase the uncertainty in the momentum. So if initially position was 5 +- 3 and momentum was 10 +- 2, then afterwards, you might know that position is 6 +- 1, and momentum is 10 +- 4. The rest of your train of thought doesn't follow after this refutation.
