I talk to people all the time who are not domainers, and to a lot of people, $2K is a LOT of money. I think domainers sometimes look at money differently than regular people, partly because so much of it is flying around. There are a ton of well meaning, regular people with hobbies and interests or a small business, who might like a good domain for a development project. There is nothing wrong with that.
A medium-sized business that might appear to have a lot of funds could easily be struggling in this economy, having layoffs etc so to them also, $2K might seem like a lot of money. Yet, they might still want to be improving their business, when the opportunity arises.
Realistically, 99.99% of people in this world are not domainers. That is important to remember if you want to sell a lot of domains. I have sold a few domains, and in my experience very few domains were bought by a speculator who then flipped them for a lot more. How often does that really happen? Domainers are 'afraid' of this happening but is it really that common? If a domainer was a stock investor, and fearful he was selling his stock before its peak, then he might never sell anything. And if you sell a domain that is sold for double a year later, that is not really flipping, that is just growing in value, so it depends on how this is assessed.
