None of this sounds like "anti-build" to me. It's more like "practical build". Anti-build has a negative vibe to me. Sounds like someone who refuses to build because they really hate it. Practical-build means not putting in effort beyond the benefits provided. These giant castles and mansions probably don't provide benefits commensurate with the time taken to build them. Building just what you need to be successful and no more just seems like practical common sense.
