GOTs- caste or tribal originators ??
IMHO it is not about "Got" per se but about Haumaii...ego..."I"ness.
A person can write his Got behind his name and still be the epitome of Nimrata, humility, ego-lessness....
A person without "Got" to identify him and trying to be "nameless" may be so chock full of haumaii, ego that it may be spilling out of his socks
IMHO the modern GOT is just an identifyer..."sticky" in forum lingo..some use their Pind (village) as identifier, some use Nom de Plumes ( Arshi is mine and as a "word" it signifies celestial..optimistic...as opposed to Farshi..grounded..pessimistic..down to earth !!..BUT there is also a caste Got "Arshi" common among Muslims in pakistan whcih get things confused sometimes as I am Dhillon Jatt and Sikh ( Dhillon is a Got and has no "word" equivalent in punjabi), some use their books, films, newspapers, famous poems, etc as identifyers, which all serve the same purpose.
The EGO in caste is primarily HINDU based...a Hindu is BORN into his caste and cannot change no matter what...a Sikh leaves his caste behind ( If he ever had one..American, Malaysian, Chinese, French Sikhs etc have no caste to begin with..) when he becomes a SIKH. The Got factor is RACIAL TRIBAL based and is a useful indicator to prevent intermarriage/incest as all Dhillons for example belong to one family, which over the years has become too large and spread all over the world but still originally from one tribe/village/area.
ONLY when a Sikh consciously avoids "soemone he pereives as "low caste" in marriage unions etc then that behaviour is anti sikhi.This is NOT allowed in Gurmat as we must see the Sikhi/Gurmatt/Rehat/Life style of our partner/our childrens partner rather than his "caste" per se.
