To keep it from devolving, I invite you to search for existing arguments in a search engine of your choice.
However, in a show of good-faith, here are 2 answers to your question:
1. Male chicks of laying varieties are ground in a macerator shortly after hatching. https://en.wikipedia.org/wiki/Chick_culling
In your fantasy, you could get around this by getting a rooster and breeding your own hens for eggs, but then what will you do with the non-laying males? What about hens who stop laying? Keep in mind, their natural lifespan is 5-10 years.
2. Hens have been bred to produce exponentially more eggs than in the wild. Wild hens lay around 10-20 eggs per year. Domestic hens lay around 250. This development can lead to osteoporosis.
