You are intentionally trying to argue that your feeling of personal safety outweighs the privacy violations that are being discussed. There is the classic quote, "Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety."

But to frame it in analogies as you are doing, it is not "a person following you". It is every person following you, at all times. A police officer, your local shop manager who is setting the prices of your groceries, your car insurer, your home insurer, your health insurer. The IRS (etc) agent assigned to you. Me, too. I'm following you, your wife, your children. You don't know me but here I am anyway taking pictures and then selling them to the user above you. Also my bank who sold me a credit card is now also following you. As well as the criminals that want to steal that credit card. Also that criminals kid, who's just curious. There's also a large man in a hat following you. As well as the person who is going to sell you your next car, they're following you too.

All these entities, and more, are following you. Carving you up as a product to sell and exploit.

And to you, you don't mind because you aren't aware. In the same way that a cow in a pen doesn't mind and isn't aware that an enormous system of industry is raising it to be carved up as a product to sell and exploit.
