There are ways to highlight the region without activating it.
You can use one of those (preferably with a different face,
if you also sometimes use an active region)..

But it's important to highlight the active region.

The "active region" has a well-defined meaning in Emacs.
Don't confuse things by talking about how you can act on
the region when it is not active in the usual sense.

Not clear, but it sounds like you do want an active region, in the usual
sense, but you want it to be active for only some things, none of which
are type/paste to replace/delete.

Much of what you describe is available with various libraries, including
`zones.el' (https://www.emacswiki.org/emacs/Zones).
