How could the use of someone's property (assuming they acquired it through just means) without their consent ever be justified? Would you consider someone buying up property around your house an act of aggression? What if they happened to do this by mistake?
I'm bored. You know what? I'll get into an ethical debate on mises.org.

No, why would I?
"What if they happened to do this by mistake?"
Then they are silly. Obv.

You don't mention "easement" at all in your post, but I'll assume you actually meant to talk about it. The point of easements is that the just owner HAS consented to the use of his property by another in a specific way. So I don't believe that you OP has anything to do with easements.
I agree with you, the question is not about "Easements". Easements are things the property owner, or acquirer, voluntarily agrees to. These would include drainage ditches, utility delivery, restrictions on the plants the owner is allowed to add, etc. These are moral actions. Now a wetlands declaration, change in zoning, take over through eminent domain, confiscation, etc are all immoral actions. (Provided the ower was not aware of these prior to purchase or homesteading.)
I think the question about surrounding property goes to the fear that out of spite or profit interest some rich dude will simply purchase all of the property around yours and cut you off from the rest of hummanity. Of course this is silly as the owner of one piece of property would have agreed to access points by other owners first. Then that same owner could reach their own property by homesteading the air above the property. Furthermore any lender would not want some rich dude surrounding their property as they would hold loans with the worthless property as collateral. The important point here is this is simply a form of Realestate Predatory Pricing. And without government support no predatory pricing scheme can be successful in the long run.
