Let's up the ante and see where you stand.

In Britain, criminals were stealing the thick, copper cables used for power and signaling of the railway. They wrapped a chain around cables near a road crossing, attached it to a truck, and dragged a significant length of cable away, to sell as scrap.

That naturally means the railway can't be used for many hours, occasionally over a day, and costs a tremendous about to repair. (It is one of the most safety-critical large systems around.) There's huge disruption, as 600 people per train every 20 minutes simply don't fit on any other means of transport.

Compared to catalytic converters, the disruption to society is far greater, the replacement cost much higher, and the scrap value relatively lower.

About 10 years ago, a law was introduced forbidding scrap metal dealers from paying cash, and requiring them to check ID. That led to a 30% drop in theft.

Is that a reasonable law?

My ass it did. I've worked in the metal recycling industry.

Getting payment in some form other than cash doesn't deter people who were already willing to commit a crime. They have a buddy scrap it and the buddy takes a cut for taking on the risk.

Yards don't want the .gov snooping around because that never leads to anything good. At the very best it's a delay and distraction. So if you come in with something the .gov is going hard on this month (cats, railway cable, whatever) they will tell you to fuck off to some other yard. And when it's a PITA to fence shit shit doesn't get stolen. That's where you're getting your 30% reduction, not the law. The government is just such a PITA to deal with that scrap yards would rather leave money on the table than have to deal with officer Donut coming by every now and then to check their books.

I’m not sure I understand why you think this reduction can’t be attributed to the law?

I think you might have a point that this law may have also deterred 30% of legitimate copper scrap transactions, if basically it made scrap dealers decide not to bother with copper at all…

They deal with copper, just not copper that obviously is rail. Bring in some old plumbing parts no problem. The only people scrapping railroad parts are being paid by the railroad.
Hmm. I wonder if steel cables would work well enough?
If you make them a lot bigger, copper is an excellent conductor. Silver is better yet, but not by enough to be worth the cost (contrary to popular belief, gold isn't very good, though it is better than iron) aluminum is often used as it is cheaper by enough, but it turns out of have weird properties and so extra care is needed to use it.
