The stylus of any MC cartridge is replaceable, by a skilled professional. I just had it done by Expert Stylus for my Koetsu Urushi. What others refer to as regards the differences in repair-ability of MM vs MC is that for MM cartridges, you can buy a completely new stylus assembly, including cantilever and magnet. Then the owner can replace the unit on his own for no added cost. I am sure everyone knows this, so what is unique about vdH MC cartridges when it comes to stylus replacement?
