AMD PSB Vendor Locks EPYC CPUs for Enhanced Security at a Cost

This entirely depends on individual's perspective.

As Chris mentioned, this is exactly what Big Corp™ wants. They'll be the ones buying it too, and would likely pay extra for such a feature. They're the target market for these vendors.

Thus, sure, for those looking to buy second hand, this is indeed advertising irreparable damage. But for Big Corp™, this is advertising security (in my opinion quite rightly so), and ensuring their data isn't stolen.

And what happens when old hardware is resold? How can anyone trust any future excorp hardware?

Well you don't. But corportations don't really care about that as much as they care about their data.

Admittedly it feels like AMD could have created something that allows the chip to be reset providing you have the original signing keys.

They should at least disclose to all prospective buyers that a current chip cannot be reset, and how to tell which firmware CA it's stuck on.
