Are you certain that people view others as tools/obstacles? What does it mean to view someone as a tool/obstacle?
From what I can tell, all human interaction is an attempt to gain something; otherwise, you wouldn't be doing it. You gain something, whether that is knowledge, money, goods and services, or just a pleasant sensation, among other things. Does it mean you view them as a tool/obstacle, when you interact with them, with the intention to gain something? Is it possible to not view someone as a tool/obstacle when interacting with them, knowing that all interaction is inherently designed to gain something?
