Dude, there is always something else going on.
Relationships are not 1-dimension concepts formed on appearances. They are complex, with many facets and details that go into it.
Have you ever seen a couple and wondered “why is someone so hot with someone that ugly?” That’s because it’s not built in looks alone. Maybe he’s confident, or rich, or a good listener, or he’s good with kids, or any of a thousand other good qualities. Realistically it’s a combination of them all, because these don’t exist in isolation. And it applies in both directions. What changes are the criteria (e g. Men aren’t expected to have perfect skin, women aren’t expected to be confident. Generally)
While technically true, this really doesn’t change the question. Life is a complex series of chemical reactions; death is what happens when these reactions stop.
Let’s say you die of heart failure. Your heart stops pumping blood. Then the brain stops getting oxygen, due to the lack of blood. Then rigor mortis, and so on. If these aren’t all fixed, you would also re-die immediately (actually, without the brain function being fixed, you would never really be alive again).
The premise assumes that all of that has been addressed by them coming back to life. Adding a few external factors doesn’t change that. If it did, the simple fact that most people are buried and would suffocate would render the point moot. Same for decomposition.
Although cremation would be awfully hard to tackle…
