I think what Ville brings up is an interesting topic that has caused a few ripples way back when with the older posters.
In the big picture view, everything is personal preference. So in that sense, nothing is wrong. Its your taste/money and you should wear whatever makes you happy. But if this site is to be viewed as an enthusiast community, where people come to teach and to learn, then there has to be a framework. No different than other enthusiasts communities (like watches, food etc). There is nothing wrong with a diamond encrusted Rolex, but I probably shouldn't wear it to my job interview at IBM.
Addressing Ville's post, there is a city/country difference in shoes, suits, shirts etc. There are also reasons for the differences, many of which have been hashed out here many times. If you choose to ignore them, that is perfectly fine (I ignore some myself) but you would benefit from knowing the "rule" in order to know how to break it. The great thing about classic menswear is that there is a large body of work that you can draw upon to see "correct" applications, and that the tools of our trade have remained unchanged for over 50 years. Suits/shirts/ties have pretty much remained the same for decades. You look at what people who are considered great dressers (past and present) wear and you take what you can from them. You adjust the choices to fit in with your lifestyle (unless you are a British aristocrat you probably can't get away with some of the Duke's outfits) and you start to develop your style from there. Its an evolving process, at least it has been for me. So what does this all have to do with what Ville said? Well, if there is no right or wrong and its just personal preference, there is no evolution. In that world, we are all great dressers, all of our choices are fine and there is nothing to learn. Scotch grain shoes are fine with a tuxedo, work boots with suits, captoes with jeans etc. What Ville is saying is that, historically (and presently), textured leathers are used in country settings. That does not mean that you have to be a slave to that "rule" but to say that its simply personal preference or a stupid rule, is spitting in the face of the Bruce Boyers/Alan Flussers/Duke/Cary Grant's etc etc etc.

I thought that was extremely well said...and it applies to so many things and so many discussions across the board. Now, having said that, bear in mind that I am not a particularly good dresser. I've been known to wear a kilt on special occasions and an Ike jacket in lieu of a sports coat. But I like the way you think--I think the logic and the reasoning is unimpeachable.
Anyway that's just my opinion and probably carries little weight in this context...FWIW.
Good on ya,
