_You_ as stylist may want to accommodate images as text. I as user would
rather there be no such thing as images as text, since they're a major
accessibility/usability obstacle. Virtually every financial or retail web
site I visit uses text in images, and they're almost universally functionally
illegible.

Images  _can_ be sized in em, just as text can be. Images that are upsized
this way and degraded in the process are _no_ worse than images too small for
the original quality to be enjoyed, which is the situation high resolution
users typically and too often face now.

No it isn't, unless the user gets to decide how big a pt actually is. You may
well know how big a pt should be, but you have no idea how it relates to an
ideal size for any particular normal user, whose screen size and resolution
you are in no position to know or need to know. OTOH, a root em is
presumptively an ideal unit, so why not use it, and forget about pt for
screen media altogether?
