And to be able to use Rosetta 2 I only have to spend the combined value of all my computers again? Double that if I want the same amount of RAM and storage as I have now
You don't have to use Rosetta 2 - that was an example of a good implementation. I did mention the announced x64 emulation on Windows, but that's only a preview release at the moment. If you're a Linux user the only thing I'm aware of is QEMU TCG but there might be faster projects out there.
