To the question "could bartering be chosen as an interesting alternative to commerce" I would say yes and no.
Yes because things are really expensive nowadays and it must be interesting to exchange things with people for two reasons and respecting two conditions.
First reason: let's take an example: friends (girls) want to change their clothes for new ones but, there is a problem: clothes are expensive. They don't really want to spend money on a top that costs 10 times the price it cost to make it. So, they thought, maybe, they could exchange their clothes. For sure (and these are the two conditions) clothes have to be still wearable, and they must cost barely the same price (if they dont it's unfair). We can do the same example with boys and videogames.
So if we turn this example in a general way, then it would be the fallowing idea: let's call A and B two persons. A needs the object C and has the object D. B needs the object D and has the object C. A and B don't want to spend money to buy C or D. So they meet and exchange. Easy!!
The second reason I found is that it is interesting to trade books, films, CD's, and stuffs like that. Because it's important for us (people), I think, to have a certain culture, and to be interested in a lot of things.
Meanwhile, bartering can be very very dangerous for economics and several other reasons.
First of all we can't (and I really think it's impossible) trade everything.
