As the subject says, is there a point to tradition? Is it just a way to stall progress, or is there value in it?
If you are talking about values and many things, I'll talk about them in the same umbrella.
Traditional values , it's not black or white (good or bad). It depends =) It's so broad, you really cannot judge it all based on brush. I think there are
3 categories:-
No value, but does not stall progress--- Having a BBQ
--- Bunnings snags
--- (Insert most religious traditions)
--- Cultural things like not doing certain things on a new year (Big with in Asian culture)
-
No value and Stalls progress--- Old traditional ideals about Chastity
--- Old traditional values about Child Raising
--- Old values about gender
--- Old Traditional values about offence and jokes
--- Literally anything regarding, sexism, racism, etc...
-
Has value--- Listening to your parents
--- Getting together for the New Year
--- Treating people how you want to be treated
--- Thanks Giving day (American thing)
--- Being kind to others and generous
--- Punctuality (Big in Asia and Europe)
....
Most people think of the things I listed in the "No value and Stalls progress" list as traditional ideals and values, but I think that there are definitely good traditional things too (other list) 
.
In short, Yes and no!
