Brief historical recap: The western cultural practice of chemical embalming originated before we had reliable 24x7 electricity and high-powered freezers and modern morgues. If there's some need to have a corpse around for a period of time until everyone can be gathered for a burial, we have the technology to do that without going through some weird pseudo-mummification chemical "embalming" process of hooking up a machine to pump chemicals into a corpse's veins and arteries.

edit: This is an ugly and uncomfortably thing to think about, but in my opinion, many "funeral home" service businesses are optimized to extract the absolute maximum amount of revenue by selling products/services to a grieving family with upsells at a time of their greatest psychological vulnerability and grief.

If you're going to bury people, there's a lot to be said for the traditional Islamic requirement (or equivalent) of basically, dig a 6 ft deep hole, wrap the person in a clean white sheet, and get them buried ASAP without going through all the rigmarole of embalming and fancy expensive casket.

You want to have a big elaborate memorial service? Ok sure great, whatever fits the needs of the family and friends. Spend the GDP of a small developing nation on it if you want to. But I truly don't see the point in trying to embalm/preserve/buy a fancy casket for a body that's intended to rot in the ground. Chemical preservation embalming and $8500 caskets are nonsensical.
