There’s no contradiction about the idea of two Ehrliche Yidden having a dispute and agreeing to settle it in Beis Din. In fact, that is the norm. Intentionally defying Halacha (as opposed to not knowing or misinterpreting Halacha) by obstructing justice and being in contempt of court by disregarding a hazmana should not be considered the default behavior of Torah observant Jews. A typical case is where both parties are seeking a ruling from Beis Din so that they can both accept the Halachic requirements and fulfill their duty in carrying out what the Torah says Hashem wants them to do, as determined in Beis Din.
