The Rules In Ayn Rand's Anthem

The rules in Anthem are very strict, but why do these rules exist in the first place? The book 'Anthem’ is written by Ayn Rand in 1937, first published in 1938 in the United Kingdom. Ayn Rand is very creative with coming up with a book that takes place in the unknown future, with Equality is being different than his brothers. The book itself is good, once you start reading the book you will suck into the imaginary world and you won’t be able to stop reading, at least that is how it was with me.
The reasons these rules exist in ‘Anthem’ is because individualism and creativity is a crime. Everyone is expected to treat everyone equal and lived for everyone, not for themselves. Selfishness is gone and the citizens are identified as ‘we’ instead
