When you're paying for every minute the instance exists, that's a long
time fussing around before you're ready to do any computing.

There is quite a bit more to it than that:

Of course it can be done with enough time and expertise. There was a
partial solution for certain HP blades, but it was never made into a
general and generally-available solution. There's a long ways to go
before VMS could be ready to spin up an instance in a few seconds, work
on some compute problem for a few seconds or minutes, and then go away.
As is quite commonly done on other platforms.
