Lads & Lassies - There have been a couple of interesting thoughts expressed in the responses so far, so I want to put in my 2c.
1) I'm really glad there are serious collectors, and I don't care where. Yes, it means that some stuff that I want I can't justify buying , but high prices most likely mean that the things will be treated seriously, and not just tossed into the boxes (where I find them). This is the best possible assurance that examples will survive.
2) There are questions about why collectors in Japan are willing to pay premium prices on EBay. Let's start with the assumption that it's true, which we can't know, because we don't really know the flow from European and US sources to our esteemed counterparts in Japan. If it is true, it just brings out again what is obvious to everyone, except perhaps Orthodox Economists: Markets aren't perfect. Not only do different things have different values to different folks, but "barriers" like trust and knowledge come into play, too. Not to mention language issues.
So, I'll remain more grateful that the items are being valued than rueful that they aren't in my tender mercies...
