1. The international schedule is crowded enough
2. There is enough domestic T20 cricket already
3. Most of these domestic leagues contain the top limited overs players in the world anyway
I am not opposed to SOME T20i matches (perhaps one on Australia day each year or something like that), but with all the T20 that goes on around the world with international players anyway do we really need a world cup and 2-3 matches in every tour? Especially with some players opting not to play T20i's anyway wouldn't it just be easier if people just concentrate on tests and ODIs, and if they want a quick buck go make it in the IPL?
