Thanks for your response! It triggered a lot of thoughts that I hope clarified things for me.
Ok, forgive me if I make no sense here, for some reason this stuff is really messing with my head.
What I was thinking after reading your post is that I must be wrong in my definition of UPB. I thought that if some behavior was the only way(aka a neccessary condition) for anyone to arrive at that goal, then that behavior must be universally preferrable for that goal. I thought that this couldn't be the whole of the definition. My reasoning was that "theft is the only way to achieve certain goals(say, somebody's wallet), so it must be universally preferable. But it couldn't be universally preferable for the reasons you were saying, so there must be another aspect to the definition that rules out theft." Then I had a realization that I think cleared it up for me. Could you tell me if this makes sense to you? Is it a helpful way for me to look at it? Or am I missing the point?
So the goal is to have this specific wallet in your possession, let's say it's mine... At first I was thinking that the only way for anybody to get it would be to use force. But then it occured to me that I wouldn't have to use force, since it is my wallet. Therefore force isn't universally required in order to get it. A similar reasoning can also be used to argue against any theft.
My origianal goal with asking about this was that I was trying to find something that was UPB according to my understanding of the term, but also violent, in order to test my definitions. So, even though I had found that this couldn't be universally preferable, I started looking for other possibilities. I couldn't find one that couldn't be answered by something similar to this. I know this isn't the kind of argument Stef uses(or that you were using), and I'm still not sure I see how that one works for some reason, so I'm still probably misunderstanding something, but I feel like I made an important step in my head with that.

Well, if we say 2+2=4, we're saying that four is the correct answer logically, objectively. However, in the realm of behaviour it is universally preferable, because it is objectively false to say 'five' is the correct answer...
...truth is universally preferable to falsehood.
Okay, maybe I'm being too nitpicky here, but I see this claimed alot and I'm not sure I've seen the reasoning behind it... Why is truth universally preferable to falsehood? Is it because truth is objectively required in order to achieve any goal, whoever you are? I'm assuming that's the reason, but I just want to make sure.
Thanks for your patience guys! The last time I felt as confused as I did the last couple days was when I was getting religion out of my head, so I know I'm working through some important stuff here.
