I think Alistair’s convenience claim is the most viable, particularly for those times when we do not check our tyres as part of getting underway.   

While a TPMS would show you instances of sudden depressurization, my personal experience with such events is they are undeniably noticeable through the handling and ride of the vehicle.   

A slow leak from something embedded in the tyre such as a screw - or my personal nemesis roofing nails - might be noticed more quickly with a TPMS, but you would still detect these through the handling of the vehicle before pressure became low enough to ruin the tyre.

Now, if the TPMS system real time display would show loss of fuel economy - in dollars and cents … I’d put them in the company vehicles :-).
