Nintendo has to do something against piracy, and unfortunately, the collateral damage is that homebrew initiatives are impacted too.

Now don't get me wrong, I buy my games for DS, which is no big deal since there's hardly more than 10 titles worth owning (and DSiWare won't change that obviously).

While I don't feel the need to "chip" my Wii for the same reason above, it is convenient for a portable console like DS/DSi to have all the games and emulators in a single cartridge.
