It looks like a big old obsolete POS/ cash register to me. But the sellers insist they will only sell to businesses. What makes this so special that us mortals are not allowed to buy, even if we had the cash?

It is a 'Prozessbedientastatur' which means something like 'Process User(Interface) Keyboard. I guess it is made for a special device. And it is stated as unused in original pakaging, which makes this (probably) vintage gear even more expensive.
As it is a device for a special device, a consumer probably would have no use for this (special protocols at keyhit etc.). So they may want to prevent shortage on this item by selling it to some keyboard fetishist who would just mod it for his desk.

Seems more likely to me that they just don't want to take returns from fools who buy it thinking they could just plug it in to their PC.

Possible aswell. Also, price might be high because of high quality components. Not in the sense of Geekhack High Quality, even higher quality. Keep in mind this things are used in serious business, so broken keyboards could mean the loss of a serious amount of money.

This is a very special Siemens keyboard indeed.
One, it's not standard communications. It uses a DB25 connector and a proprietary protocol.
Two, it's a safety (OSHA, etc) compliant lockout capable keyboard for automation systems. That's why the key is there.
It specifically goes to a Siemens Simatic S5 (http://www.automation.siemens.com/mcms/process-control-systems/en/simatic-pcs7-migration/simatic-s5/pages/simatic-s5.aspx) or "Step 5" system. The S5 still runs hundreds of factories, including pharmaceuticals.

thank you, rootwyrm!
Again the combined wisdom of all geeks has proven incredibly informative in this specialized field!
Yes, I can see why they don't want to sell to individuals. It makes sense if something is out of production and businesses desperately need it still.
but I'm not sure what could be 'higher quality' than geekhack level. Aren't buckling springs (and beam springs) already THE standard for lasting quality? Unless you're talking about keyboards for scientific instruments intended to survive radiation and ultra high temperatures?

Well these things are not like 'ok cool my keyboard lastet 5 years, pretty impressive'. If this would break after 5 years in any way, Siemens would be in trouble. These things are meant to last and _never fail_.
