My personal ethics apply to how my actions impact other living things. I don't lose sleep worrying if I've wronged an entity created solely for the purpose of maximizing shareholder value.
I'm honestly surprised how many people don't agree with that. To each their own I suppose.
Edit: You're totally right about the futility of trying to shove all of us into any one descriptive bucket though. That was a mistake.
You're advocating for stealing from businesses. When enough people like you do this, it results in either higher prices for honest people or the loss of a service entirely.
At some level, most people think everyone else thinks and behaves similarly to them, and are surprised when they find out that they don't. That's why projection is a thing.
Because in the end, even big evil mega-corporations have human stakeholders. For some of them that's their livelyhood. Not everyone is in it out of greed.
Not that sneaking into airport lounges is some huge theft, but acting like it's completely okay isn't cool either.
