The whole notion of storing eggs is an old one, so lets not poo-poo it too readily. WE here tend to be in a microcosm, looking out and shaking our heads at those "non-chicken" folks we see. But eggs were around long before us, and have been esentially seasonal since their inception. The desire to preserve their goodness, long term, was strong.
There are the preserved eggs common in Asian cultures, salted and pickled eggs seen elsewhere. You can even store them in a solution of silica dioxide, called 'water glass', and they will keep up to 9 months without refrigeration. That was known in the 1800's and was fairly commonplace.
When refrigeration finally came along, it was a real boon to the egg man and consumer alike - now eggs could be kept for months, well into the off season. This meant higher prices for the egg man and eggs available to the market when previously there had been none, or very few.
Are they fresh, fresh? No. Are they serviceable and better than no eggs at all, especially for those who can't or don't produce their own? Certainly.
