Actually, the goal is to make content which attracts and retains visitors, and if your site is commercial turns them into buyers. RSS feeds are fine to supplement your info but don't kid yourself that you will do well if they're your sole or main focus. You'll get lost in the sea of many other sites which have done the same. Look at all the cookie cutter SEs which gobble up popular domains and litter the net. Do you use any of these on a regular basis or turn right around and leave like the rest of us when you unexpectedly hit one? That is how your site will come off to others if you go all RSS feeds only. Dynamic sites do not necessarily mean duplicate information. Many go this route if their site has more than a few pages because they're far easier and quicker to maintain and keep up-to-date. RSS is a great tool to get reciprocal links from others as well as advertise yourself since you offer real content instead of just another empty link.
