Buyers asking for everything in the inspection to be fixed

We're selling our starter home, it's in great condition, sought after neighborhood, best school districts in the city etc. Multiple offers from the first day of selling. New HVAC and water heater, roof has 8-10 years on it, professionally painted, updated appliances, new gutters. We've done more than $50k worth of improvements over 5 years.

The buyer's inspection report found 1 safety issue (attic hatch Sheetrock depth is 1/4 inch short vs code), a few roof fixes (replace some pins, new/painted dryer vent cover) and a mix of minor issues (some caulking, stove hood light bulb replacement, 1 window screen has a small hole). It's well below the level of findings we or our realtor have seen in other inspection reports.

The buyers have requested that every single item on the list is addressed.

We first countered offline by saying we'd offer a $1k credit, which was the price of the attic hatch + roof repairs, or we could do these ourselves before sale. Their preference.

They came back asking for $4k credit stating that is the contractor value of all elements they will "need to" fix.

We've asked our realtor to counter and say we'll do the hatch and offer $2k credit, but to be very clear that this is exceptionally generous given they are asking for repair of minor cosmetic items that are signs of normal wear and tear. I've also asked her to highlight that we are frustrated.

Basically, I'm more than happy to put the house back on the market over this. We're getting into the spring period, we know that inventory in our price range is low and we're comparatively high quality, so I've no concerns we'll get a quick sale likely over asking.

Before I go all the way, I wanted to sense check: are these buyers being as unreasonable as I think they are? Are we being generally fair in our counter offers?
