Hypothetical comment follows...
There is no middle ground with theft/piracy.
If you want to be legal then buy the licenses you're supposed to buy.
Or steal everything - only your moral stance can make that decision for you.
Surely there is a practical, if not legal, "middle ground", which (knowingly or otherwise) is exactly where the OP is standing on this issue. Purchasing 1 license is better than none, but not "as good" (or "as legal") as buying 2.
What about a small business environment who have 50 Windows licenses, but for various reasons find themselves running 54 Windows PCs for about two weeks, while moving some users from one office to another. Legal? No. But also far from "steal everything", which is the only alternative according to you.
What about John, who buys every piece of software on his PC, but can't afford a license for Photoshop. He doesn't actually use Photoshop for anything, but every now and again he is sent a file in PSD format and needs to convert it into something his preferred editor (say Paint.NET) can use, so he installs a pirated copy. Legal? No. But again, it's a little different from "steal everything".
This is all hypothetical of course, since using illegal software IS wrong and none of the above situations are valid reasons for doing so. I just wanted to comment that even though your moral code only allows for the extremes of "legal" and "steal everything", this is only one point of view.
Legally you are correct - it's all or nothing.
