The problem with that line of thinking is that it paints systemic problems as somehow more justifiable than non systemic problems, it implies they were so convinced they'd always be able to track everyone as much as they like with no oversight that they built a machine with no off switch.
But this isn't new, these complaints about privacy and tracking have been around a decade, they didn't build facebook before anyone knew the constant tracking was controversial, they built it over a decade+ knowing the whole time that they were the subject of constant criticism.
They have switches all over their site for things like turning off targeted advertising, and they have entire infrastructures for dealing with local laws, so they idea that it's unfeasible for them to remove the tracking for any reason other than they wanted it to be that way is bordering on dishonest.
I would just go for using height like you mentioned, if you, an average person is 6ft tall, someone with a better job than you would be up to a foot taller than you, a millionaire would be tall building sized and a billionaire would stretch into space.
I guessed all of these values, I might do the actual math at some point, but not right now.
