Rather than us fighting for the right to repair, shouldn't manufacturers be fighting for the right to limit our ability to repair? Isn't "right to repair" the default state? The right to repair, modify, disassemble, recombine your own property is a key component of capitalism, is it not?
If people wish to voluntarily trade vehicles without the "right to repair", that's their choice, that's capitalism. The state intervening in transactions one way or the other is a violation of the capitalist ideal.
