I have numbers to *dispute* these claims.

I'm really not worried about IO or SSD life from /tmp usage.
I see what you're trying to say, and I tend to agree with you, but the amount of space consumed at any one point in time does not reflect the amount of IO going on on that file system.
the IO on /tmp in most worksloads is practically meaningless
in workloads where it becomes meaningfull you do NOT want to have this hughe data in tmpfs because it is too large
there is a reason why applications are creating temp FILES instead store anything in the memory
