My father wants to pay for a family tomb so that when I die, I can be buried there as well. Do I let him or try to stop him?

my father is religious, I'm not and I don't care what happens to my body after I die. Burn me, use me to feed stray cats.

To me, wasting money to buy a plot of land so I may be buried with them when I die is a stupid idea.

It is, however, his money. Who am I to disagree with him?
