I want to make a +- 2.5V rail from a 5V supply using an op-amp. I was wondering if I could use a totem pole for driving the output like this:

But while I was looking at it, I noticed that since both transistors need to be (almost/close to) half way open, they will act like a resistor and will just sink current to GND (the original GND) even if I do not use the new "Virtual GND)
Am I right? None of the tutorials I watched mentions this.
Also, which is my return path for current for the devices I power from the new "Virtual GND"? Is it the Virtual GND or the original GND?
I need to understand this in order to know where to connect the copper pour
