Rubbing is an inherent issue with bicycle disc brakes. Why do you think the question gets asked so much? It's not impossible to avoid, but with some systems it's extremely difficult to achieve.
4 disc brake bikes in my house (1 hers & 3 his), none of them rub. My 3 bikes have a combined 20,000+ miles over 10 years. If the pads are rubbing, the calipers need to be adjusted; if your brakes don't allow you to adjust the calipers, you have the wrong brakes and need to replace them.
The question is asked so often because disc brakes are 'new' to road bikes. The MTB people aren't asking, 'cause they've been using disc brakes for 10+ years and figured them out.
