Is it? Can’t say I’ve really noticed it.

In fact just today I read this article in my EU country that sounds almost identical to what this comment describes:

“ If, for example, the payment was made by credit card and the product has not been delivered, the consumer can contact their credit card company directly and request a refund.

Credit card firms can usually refund the money quickly, Beurling-Pomoell noted, whereas consumers who paid by debit card must try to claim their money back from the bankruptcy estate.

"Unfortunately, [reclaiming money from a bankruptcy estate] is usually a very long and difficult process. Consumers are generally in a relatively weak position when a company goes bankrupt," he said.

Beurling-Pomoell added that consumers should always consider using a credit card when purchasing a product that they do not immediately receive.”

I think some examples are in order - where has the UK, having recently left the EU, changed its laws so that it was completely out of step with consumer protection? Or is this one thing that made it necessary for them to leave the union, perhaps?

If a pan European system takes off, it’ll be interesting to see what happens with the UK.

Their self-harming has been impressive.

The "consumer protections" of the EU basically amount to communism (i.e., state interference in private matters). So no, that's not a thing the U.K. should emulate.
