Tanenbaum pointed this out a couple decades ago with respect to AT&T:
At one time, 80 percent of AT&T’s capital value was the copper in the local loops. AT&T was then, in effect, the world’s largest copper mine. Fortunately, this fact was not widely known in the investment community. Had it been known, some corporate raider might have bought AT&T, terminated all telephone service in the United States, ripped out all the wire, and sold the wire to a copper refiner to get a quick
payback.
I guess that approach would have seen the price of copper sink rapidly and very deeply, as it would remove quite a bit of demand and would introduce a new supplier.
You do not have to do much digging. Choose to end points not too far from each other. Cut the lines on one end. Attach a strong string on end A. Pull the wires from end B. Now you pulled the wires, and you also have a string that can be used later by another company wanting to use the tube (which you will sell btw).
Before you consider buying a company and selling off its assets, you have to realize that when you own a company you also own its debt, and that if you liquidate you have to pay off all that debt (unless you can pocket the cash and file for bankruptcy, not generally legal).
This info is publicly available and quite a bit more accurate that the Register's napkin math.
As of March 31, 2011 (end of BT's last fiscal year), they owned $23bln (that's USD) in "Property Plant & Equipment" (including all the copper in question) and held $35bln in liabilities.
I used to think that designing railway signals must be the hardest problem in engineering, because every time I'm delayed on a train (a pretty common occurrence in the UK) the announcement blames it on a "signal failure".
Then I found out that the problem is caused by an epidemic of metal theft on the railways!
It's becoming a big problem in the UK - my parents phone and broadband was down for about a week when their (rural) wires were stripped. The thieves get a truck, tie on the cable and drive, rips the whole thing out the [shallow ditch in the] ground, wrap it up and sell it ... then they come back a week later, when the cable has been replaced, and do it again.
Someone tried to steal the gas pipes from a business premises in my city, left gas leaking in to the building for 24 hours or so, didn't even manage to make off with the pipe. Morons.
I worked for awhile at a local power coop. My boss had to go into court one day because someone was caught trying to steal copper from a substation. The guy was lucky he didn't kill himself.
People do die for it[0] [1]. Not to sound too flippant but the lengths they go to just to steal some wire is genuinely shocking. Do they not appreciate the dangers?
A lot of railway signalling is now done over fibre optics for this reason, with the odd side-effect that a number of rail companies are moonlighting as telcos.
It wouldn't work in practice. BT is legally required to provide phone service, so you couldn't just buy the company and stop providing phone service on economic grounds.
Telecom companies (including cable operators) are all about cash-flow. When you have a solid subscriber base, there's not an issue with carrying a lot of debt. What is a problem is that the younger generations aren't tied to having a land-line and the older generations are gradually following suit.
If I knew what an "attention metal" thief was, or just "attention metal", I'd agree.
Effective sarcasm demands flawless execution, and they're losing that. Nowadays one can often find misspellings and sundry grammatical errors in their texts.
How about pulling fiber through instead of a string assuming the copper is worth more than the fiber? Clear some debt as well as covering the cost of the fiber and upgrade the network at the same time.
