Do we not consider the loss of information due to subsampling as well? Or are we only focusing on loss due to blurring

If the images are sufficiently blurred, subsampling will not result in an additional loss of information. When it comes to reconstructing this images (as described here), it is this reason why the subsampling operation is invertible. This may become more clear once we finish this lecture on Monday and discuss the Nyquist limit.
