To the OP - Save your money and get better results yourself by using the correct technique with good quality products (even a brand new car can often benefit a great deal from a good detail, and will keep on looking good for longer).
To Dubya - Roughness to touch (or for a better test, sliding your hand inside a thin plastic bag across the paint) is a good indication of external contaminants on your paint - leave them there and they will damage your paint. The more you get the worse it is. I had a bad case of rail dust on the roof of my van (from new). It was an absolute PITA to remove. If it had landed on a layer of sealant or wax it would have been much easier to remove.
If you think leaving your paint unprotected is a good thing then I'm not going to spend too much time trying to persuade you otherwise. Many, many knowledgeable people disagree with you, spending lots of time and money protecting their cars (and they look better afterwards too).
It is up to the individual what results they want, and what time, money and effort they are willing to spend to achieve it.
Personally I like a good sealant (I'm currently waiting on my shipment of Jeffs Werkstatt acrylic sealant), but if my car or van was subject to frequent bird or bat poo attacks I would also add a layer of wax on top of the sealant, as it gives the best protection from these flying krapp producers.
