Camshafts, idle quality, driveability and LSA-REAL WORLD EXP and OPINION

I agree with the above statements... "build with the cam that will work the best, perform the best". But that's me......
However, is it really wrong if somebody wants to build for a sound, and couldn't care less about performance??? What if they only like the mean sound, but have no interest in ever opening it up???
- Is it wrong if somebody mounts a dual snorkel hood scoop that's not functional but only for looks?
- Is it wrong to put wide tires with traction bars on a stock slant six car though it's not needed, but does it for looks??
I say we all have different desires and interest for our cars.
