Do you really mean to imply absolute adherence to the law, even unenforced laws, is a requirement to be a principled person? Does that mean all laws in all countries or are the laws of your country the most principled ones?

In some US cities it is literally illegal to feed the homeless. In every US city it is illegal to go on mile over the speed limit. In some countries it is illegal to not turn in your neighbors for being gay.

Be careful with confusing legality with ethics.

Nope I'm not implying that, but you certainly inferred it. Legality is one marker you can use when deciding ethics, especially in a democratic country. Also we're talking about the permissive side of the law (reselling used books), not the restrictive side (not being allowed to feed homeless people).

Maybe: "In some US cities it is literally legal to apply eminent domain to kick people out of their houses to enlarge a freeway" would be a better slippery slope, but that's still a totally different power dynamic.

So yeah I dunno. Try to come up with a better analogy, but definitely keep to your slippery slope. It'll convince somebody.

The onus is on you to argue why, in the case of piracy, breaking the law is moral. With feeding the homeless etc the argument is clear.

Easy. DRM restricts freedom and privacy in ways I find intolerable and will not financially support. Borrowing, piracy, and buying first or secondhand paper books does not have these problems.
