This is the wrong way to look at it. You're not thirsty for resources. You're protective of them. Imagine if you were aware of giant, angry Americans who were flying to Japan to steal all of your coke and convert all your land and resources into coke manufacturing plants. Do you let the plane in? Do you stop it from traveling at all? Do you glass the surface of America with nuclear weapons? How do you know they won't do it to you?

But that makes no sense. You're spending resources protecting against a scenario that is effectively impossible. The term for that is paranoia. Plus, it doesn't even make sense to try to "protect" yourself because their first move if they even thought like this would be to nuke everything flat with no warning. There's no defense against it. You can't hide either, the signals are already out there, they know where you are.

    Even if they don't think the same way we do they are (probably) bound by the same laws of physics. Obviously this argument doesn't work if they have developed warp drives or infinite energy sources and reactionless engines, but if they're bound by the rocket equation as we are then there are truths that can't be avoided. We are on the cusp of being able to detect the biological markers of life on distant worlds by spectroscopy. An alien civilization that can traverse the enormous gulf between solar systems can very easily build widely spaced telescopes that can monitor all nearby solar systems for changes to atmospheric composition. Anybody who is paranoid enough to need to kill any life around them would obviously build such an array. There is no hiding from them, the technology is much too simple compared to what you need to travel between solar systems.

Maybe they can't themselves, but don't like the idea that someone else eventually may be able to. I think you're overconfident of the safety of actively advertising our presence to the universe because you're making a lot of assumptions and only considering a small number of possibilities. The problem is that there are so many unknowns and so many shades between different possibilities that no one can really be confident about anything, except that the risk could be anywhere between zero and the maximum.
