Funerals have purpose. Family members can gather to mourn and get closure. This is not superstition. I never even remotely suggested that it was, nor did I say that we should forget people when they die.
You're saying I said something I didn't, then arguing against that. That's a strawman.
On the other hand, preserving bodies for centuries by embalming then encasing them in an airtight tomb, as is the modern practice, is simply modern mummification. There is no afterlife, therefore no reason to preserve the bodies this way. It's also a huge waste of land and resources. It is stupid.
Cremation is less stupid, but more creepy. I mean if a funeral is for closure, then why keep the dead in your house? And how many generations are you expected to keep? Should my father pass down his father's ashes to me, and I pass them on to my kids, and so on? At some point, you've got a closet full of jars of human remains. That kind of crazy only happens for religious reasons.
By all means, have a funeral, say goodbye. Then let the city body disposal service take it away and make compost out of it.
It only seems offensive because it's new. I'm sure the first guy who said "Dude, let's set your dead mom on fire," or probably got some disapproving looks in his day.
