Because it isn't cheap, first of all. If you wanted to run a completely secure internet, for example (a problem I am currently working on) the cost of all those RSAs really DOES show up, and fast.
Parry, It looks like you have your own agenda in which large rsa keys doesn't fit your time constraints. Don't implement large keys for your secure net. And don't convince yourself that it be COMPLETELY SECURE. -tom

It will be no less secure than one using larger keys. This point is lost on you, of course. Perry
Rumor has it that certain government applications do Diffie Hellman with 2K-bit moduli. Given the apparent connections between factoring and discrete logarithm (the complexity formulas seem to look very much alike), it appears that at least one user feels that keys longer than 1K bits provide a desirable safety margin.
