What is the likelihood of seeing another macbook with no stickers compared to the one with the exact same stickers as yours arranged in the exact same way? I think that should address the issue with your argument.
It's the one next to my shoes and my wallet.
I think that's how pretty much everybody does it
Though every MacBook has some small details that can be picked up even if "identical"
I usually put my carry on (a rolling bag) and personal item (backpack) on the bookends of other bins/belongings on the belt, s.t. all the bins are between two large, distinctly-mine items. It also makes pointing out the items which are mine to a TSA agent significantly easier.
I live in Europe, you need to put the laptop into a plastic box, with all the cables, etc. It's easy to identify it. I put also personal belongings
