stubborn, obstinate, intransigent
傢 centers on a rigid, unyielding attitude: being stubborn, obstinate, or refusing to change one's position.
傢 combines 亻 (person) with 家, but the historical development is uncertain. It may have originally expressed a person with a settled, unyielding nature, though this is speculative.
A person 亻 who acts like a house 家: immovable, set in place, and stubbornly refusing to budge.
For カ, imagine a stubborn person blocking the door of a house, shouting 'Can't!' — the 'Ca' in 'Can't' cues カ, and the person's obstinate stance fits the meaning.
