What are the costs? That someone hacks some system with they legal name attached to the hack?

Nex the UK will ban knives. Oh wait...

The potential cost is an XSS vuln.

... with the name of the perpetrator attached. Companies are not something you can register anonymously.

Do you have bars on your windows? No? The potential cost is a breakin?

You you expect restaurants and stores to pat you down before you are allowed to enter? No? The potential cost is an attack on the staff.

Should we ban cars because they can be used as lethal weapons? No? The potential cost is a terrorist attack.

Deterrence through consequence is a thing and generally less costly for society than to make crime 100% impossible.

> The potential cost is a breakin?

Absolutely. In exchange, however, I get better visibility, and lower cost windows.

Those advantages are meaningful enough that my house does not have bars on the windows.

Isn't that more a statement that you're lucky enough to live somewhere that you don't need them? The real question is how many home invasions would you put up with before hardening your security, in more ways than just bars on your windows?

Yes, in different circumstances, I would have bars on my windows.
