Why have rules or boundaries in life if they are not enforced? You might as well not have them. Chaos will eventually ensue but that is expected.
Having rules and boundaries and enforcing them occasionally or intermittently or inconsistently is another path to disaster. No one knows if they are true or worth respecting or if they can get away with things.
Again chaos will ensue.
Have sensible rules and boundaries and enforce them. That is the ideal way to go.
