I agree, this is a strong theoretical argument. Not really a practical one in my books.
Hmm, I guess I'm not sure what you mean by that. I hope it's not a "yeah, that makes sense, but it'd be inconvenient for me, so I'm going to ignore it" argument?
Perhaps illustrating it with a different example would useful? Say you have a friend who invites you to dinner out, and tells you that "this is my favorite restaurant! I always get free food here, it's great!"
"Free food?" you ask, "how do you get free food?"
"well, they've got this policy, where if you're not happy with your meal, you don't have to pay. So i just eat, tell them I'm not happy with it, and I get it free! It's great!"
"Oh...isn't that, like, stealing or something?"
"Nah, it's there own policy. It's their fault for having it if they don't want me to eat for free. Besides this place does really good business. A few free meals isn't going to hurt them."
"But, you you're not actually unhappy with the meals? I mean, you eat them all, and say it's your favorite place to eat."
"yeah, yeah, you just have to tell them you're unhappy with it. You don't actually have to be unhappy for real. I mean, how are they going to know, anyway, right?"
This is a situation where I assume we both agree that the friend is acting unethically. But they keep getting away with it, the restaurant seems to be doing fine, and the friend really likes doing it and considers it fine. How would you go about convince them that what they're doing is wrong in a "practical" rather than "theoretical" way?
