1) First you said naked long options for $1000, and then it's spreads for $1000. Which one is it? Obviously spreads for $1000 is a smaller position and less risky than $3000. But that wasn't the point.
2) and 3) I agree with what you're saying, but it's not really about the stop-loss orders. When you take a loss, a wide and fast-moving market aside, that's the risk you're taking. You have to have a rough idea of what the worst case may be - sometimes zero of course, but sometimes nowhere near that. And in those cases the premium isn't the risk. For a spread I'd say the risk isn't for the position to go to zero, unless it's very near expiration.
