What? It sounds like the problem is they didn't have enough information about you.
If they had more info, they could avoid blanket policies such as avoiding riskier shipping options with all new customers, and use with customers they can prove are not fraudulent.
But here's my anecdote:
I bought a metal collar extender at Macy's with my credit card. It was an impulse buy at checkout and I have never searched, emailed, liked, etc. this product in my life. I get on Amazon a week later and I have a recommendation carousel of metal collar extenders. I was so surprised I even checked my email for a receipt to see if that's how Amazon retargeted me [there was none].
But then I just stopped caring, because I realized that if anything Amazon was incurring an opportunity cost for not recommending me something more useful, and I have more important things to do with my time than to worry about how I'm being retargeted on Amazon.

That is part of my point. It will never be perfect, but perfect enough to get a benefit for businesses. If this leaves you as part of a small percentile at the road side, that is your problem not their's. In the end, you may be regularly unfairly disadvantaged because of it nevertheless.
This is an example of a Nirvana fallacy - where you are saying it should be abolished because the "perfect solution for everything" is unattainable. If anything, your anecdote proves that should be made even better, not abolished.
Besides, the business lost a customer with you, so it's obviously not perfect enough for them either.
It is incredibly easy to see where your anecdote could go wrong. What if you had bought something much more personal or embarrassing?
Condoms? Plan B? Dildos? Lube? Imagine having to explain to a family member sitting next to you why those items are showing up in your Amazon recommendations.
I recall an example a few years ago about a store's marketing system telling a father that his teen daughter was pregnant before she ever told him. Because the store's system had correctly inferred from her previous purchases that she was pregnant and started giving recommendations for stuff like diapers.
Suppose a homosexual in the closet was buying sexually explicit things or an atheist in a religiously strict home or country was buying blasphemous materials.
Ironically, your anecdote presents much worse scenarios than the parent comment's anecdote.
Slipping down the slope of embarrassing adult toys shows a lack of understanding of how these networks work.
Again, this isn't a problem with retargeting. What if I just bought sex toys directly on Amazon and they made product recommendations for it while I was browsing at work? Or what if Facebook and Google showed me adult ads while reading Forbes.com?
That's on Amazon et al for displaying adult sex toy recommendations. Same as your nightmare scenario of where I'm a persecuted homosexual in Saudi Arabia, and Amazon makes homosexual product recommendations to me while the religious police man is looking over my shoulder.
"That's on Amazon" but you're bearing the consequences. What consequences would there be in the nightmare scenario for Amazon? None. They get the power and not the responsibility.
They have your problem now and already address it. It isn't unique to retargeting.
They lose customers. Ad networks lose websites. Walled gardens lose users.
That's why you don't see promoted dildos on Amazon, Forbes, and Facebook even now - and why your nightmare scenario is just a bad daydream about rubber cocks.
I replaced a leaky kitchen faucet with one I bought online. For weeks afterwards, banner ads for that exact same faucet kept appearing everywhere. Did they think I had two kitchens?
I notice the targeted advertising all the time, and I've never been tempted to buy. Their predictive algorithms on what I'd like to buy next are hopelessly wrong and often (like the faucet) simply incompetent.
If they had more info, they could avoid blanket policies such as avoiding riskier shipping options with all new customers, and use with customers they can prove are not fraudulent.
