Since I pay to receive the mail, and it's my domain, I'll reject anyone I like,
thank you very much.  You are thinking in terms of a large free email provider
like gmail.  Spam may eventually drive large email providers out of business.

Recent trends (and current business strategy at some large ESPs) suggest the 
opposite.  Large ESPs are growing, while smaller ESPs and ISPs that provide 
email as a sideline, are going out of business.  The thinking at the large ESPs 
(and large spam appliance companies) seems to be that effective spam blocking 
is their competitive advantage, and it takes a really large company to do it 
right.  

Part of the large-company strategy, unfortunately, is to hide problems with 
lost mail.  Given current conditions, I use yahoo.com for my Transmitter, and 
my own "hobbyist" MTA for receiving.

As for reject policy, it should be the Recipient that decides whether to send a 
challenge, a normal reject, or use a quarantine.  There should be a sensible 
default set by the Receiver for recipients that don't know or don't care.
