Why do the shortcuts I take on a build feel like a moral issue?

You are beginning to see your shortcuts differently, not as a business calculation but as a moral one. That shift is worth trusting. What you build shelters people, and once you truly feel that, a cut corner stops being about margins and starts being about the humans who will live inside your work. This is not guilt to argue away. It is your conscience catching up to the reality of what you do. A shelter is one of the most basic trusts one person can build for another, protection from the storm, safety for sleep. Treating that carelessly is a moral matter, and you are right to feel it as one. Let the new awareness change one thing on your current job. Find a corner you were tempted to cut and do it properly instead, thinking of the family who will depend on it. You do not have to overhaul everything at once. You just have to let this truth start guiding your hands, one honest choice at a time.
