Fair point, but IVF are a single new person, not an existing one you'd copy.

You're also walking among many, many real-life clones. They occur naturally at a rate of about 1 in 400 births.

This is what I was looking for. I mean... Twins right. Sources are great though. Sauce?

[thaumasiotes]

My mother is an OB/GYN, that's where I get the 1 in 400 rate from. Quick googling will tell you that the identical twin rate is 3 per thousand ( https://www.verywellfamily.com/identical-twins-2447126 ) or 4 per thousand ( https://twinsmagazine.com/incidence-of-twins-by-twin-type/ ), or half the rate of fraternal twins (the first link again, but this is false -- the rate of fraternal twinning depends on the parents' race, but the rate of identical twinning doesn't).

Why would you consider a clone to be a copy of a person? They share genetics, but not background, childhood memories, development, etc.

Are you also scared of twins?
