mos yumos, while that may be true, let’s look at it the other way. We all do millions of mitzvos, and we get rewarded for each one.
And in general, why focus on the negative and make everyone miserable? Even in the OP’s post, the entire thing can be said with the focus on the positive instead of the negative. Which would mean that the walls, doors, and windows of our houses, workplaces, etc. all testify for us about the wonderful things we did, even while no one was around! It would actually give us an incentive to do mitzvos and chessed without needing it to be recognized or seen by anyone.
