It’s sort of interesting how Odo (as a proxy for the writers and audience) mocks the Ferengi death ritual.

Those traditions aren’t actually that far from how the bodies of many Christian saints or other holy peeps were treated a few hundred years ago in Europe. Their different body parts could be taken to various churches or other places to which you could make a pilgrimage. So you might go to see St Whoevers left elbow or St Whatever thigh bone. 

This was the tourism of its day. Probably brought a lot of revenue to the cities that had these remains, as it created a lot of commerce. The Ferengi are just a bit more direct about the profit aspect.
