You're mashing together two groups. One claims having swap is good actually. The other claims you need N times ram for swap. They're not the same group.

> Memory is limited either way; whether it’s RAM or RAM + swap

For two reasons: usage spikes and actually having more usable memory. There's lots of unused pages on a typical system. You get free ram for the price of cheap storage, so why wouldn't you?
