I'm still waiting for anyone who shares Donald's and Kirian's objections to my earlier logic to present them in not-insulting terms. Until then, I don't have a lot more to say on the topic in general, as I think we've all repeated ourselves enough by now.
I don't know why you think someone will explain how you are justifying immorality without insulting you. Do they start off with a speech about how morals are arbitrary?
Morals are arbitrary. There are a bunch of atoms moving around, and later on they are in different positions. What are morals, in this context? Mere high-level abstractions.
Also, here's a handy way to justify whatever evil thing you were going to do anyway:
1. Everyone likes to be able to trust each other and treat each other without suspicion.
2. People like to win.
I know, right?
3. People sometimes succumb to the temptation to secure advantages via illegitimate means, especially if they are 100% certain that they cannot be caught.
For example, it's advantageous for your wife to cheat on you. Maybe she'll get pregnant and increase the fitness of her offspring. That's no sleight against your genes; genetic diversity is one to one with genetic fitness. It is for sure better to cheat on you.
4. The point counter can be trivially modified to be undetectable. As blueblimp points out, at present there is no reason to believe anyone has done so (but neither is there particular reason to believe that they haven't).
Similarly your wife can trivially cheat on you without you catching on. You can try to argue against this, but man, you are at the office all day, and it's a long commute, and she's always out buying groceries or getting her hair done or something.
5. Even if no one is actually cheating, the existence of an easy and undetectable way to cheat breeds suspicion and resentment.
Even if she isn't cheating, the fact that she easily could breeds suspicion and resentment.
6. It also provides an incentive for otherwise honest players to begin cheating - "My opponent is probably using an undetectable point counter, I guess I will too".
For all she knows, you're probably cheating on her, with some floozy at work. Why not also cheat on you?
7. The only resolution to problems of unenforceability is to legalize the unenforceable action.
The only resolution to problems of unenforceability is to legalize the unenforceable action.
8. Therefore, to maintain the trusting nature of the community, and to avoid providing unfair advantages to those willing to cheat in undetectable ways, the extension should always be legal in competitive play. This is an unfortunate conclusion for those who have a strong preference for Dominion play without the extension, but I believe it is nevertheless an inescapable fact of online life. The alternative is to incentivize and reward unethical behavior.
Therefore, to maintain the trusting nature of the community, and to avoid blah blah blah, your wife should be free to have sex with whoever. This is an unfortunate conclusion for those who prefer monogamy, but it is an inescapable fact of modern life. The alternative is to incentivize and reward unethical behavior. And we wouldn't want that! Then people would do unethical things!
It's a neat trick that you can solve the problem of "x is unethical" by saying "let's redefine x to not be unethical." Problem solved!
I have nothing against people with open marriages or people who like point counters. Your argument is crazy nonsense though, and it turns out humanity is better than that.
