...slabbing is detrimental to the hobby??

It does not seem from what I am reading that any reason would be good enough to change your mind.
IMO, there is nothing wrong with that.
There are 3 kinds of people here The "Fers", The "Undecided", and The "Agins."

Sounds like you are one of The "Fers"
IMO, there is nothing wrong with that.

But, I don't see any of The "Agins" calling you names, threatening to sue you, bragging how they have the best chips in the world, how much they spend for chips or calling your chips crappy. Sounds like you might be in this thread to tell us what a BIG chip collector you are.

I have found some of the best people in the world in this hobby. Some collect cheap chips, some collect big ticket chips. But they are all chip collectors.

As far as slabbing goes, I am one of The "Agins."
IMO, there is nothing wrong with that.
