I have a hard time believing this, are you suggesting that it is perfectly legal to run pirated software so long as you never entered a license agreement with the creator? Or that the existence of a license you've never interacted with and potentially have no knowledge of has an impact on the legality of you running pirated software? What if a company's internal software is leaked, surely they have the right to prevent other companies from using it?

I am not. Of course it's not legal to use pirated software. By definition pirated software is illegally obtained. But a legally obtained copy can be run without a license, if none was required to obtain the software.

As for "leaked" software: again, if copies are illegally obtained then of course it's illegal to use them.
