If you only use them for baking, you won't notice the deterioration of quality so much. As long as they're not actually bad, you can still use them. But you can take eggs out of the fridge a while before using them if you want them at room temperature for baking. 18 degrees is still too high to keep eggs fresh.
I like to poach eggs sometimes. You need a fresh egg otherwise it doesn't hold together in the water. I also find older eggs which have been stored for weeks at room temperature (like supermarket eggs) have an unpleasant taste.
I never buy supermarket eggs. I'm lucky that I can buy eggs from smallholders near where I live. They're never more than a few days old when I get them, then they go straight in the fridge to keep them fresh.
Apart from the quality (taste) issue, pathogens multiply much faster in a warmer environment. This is less of an issue now that most hens are vaccinated against salmonella, but other pathogens are available.
You can keep eggs out of the fridge, but why would anyone want to? There are no benefits to not refrigerating them and quite a few negatives.
