I agree with the “in everyday applications” qualifier. But there are plenty of applications that are research focused where having access to a proper quantum computer would be useful. As a Quantum Circuit fundamentally models a Unitary transformation on some quantum state it is hugely useful to model the time evolution of quantum systems which are experimentally difficult to access using a quantum computer.
Oh the ordering and lack of commas in my phrasing made it my point unclear. What I mean is: using a quantum computer enables simulating quantum systems that can otherwise not be simulated in a reasonable time (using a conventional computer) and that is especially problematic if those systems can’t be experimentally looked at easily.

You mean "... using a conventional computer"? (Excuse me if you didn't mean that.)
