Unless the main goal is to participate in homebrew competitions where the style guidelines actually come into play, fussing over style guidelines with any rigidity almost sounds antithetical to the spirit of the hobby, IMO.
But with that out of the way, I definitely think there is benefit to going through the exercise of brewing some beers "to style" so you can learn firsthand what makes certain styles tick. Over centuries of beer-making, "styles" develop for a reason - the collective wisdom of brewers shows that certain groups of ingredients and processes tend to produce results that are reliably desirable when used together.
It has direct parallels to lots of other creative hobbies - cooking, photography, songwriting, etc. Learning the "rules" first and then making deliberate decisions to break them is always a better approach than just flying willy-nilly from the get-go.
