I'm afraid I'm still not understanding you.
You can copy and paste products.  But products can only live
in the Products folder.

This restriction is due to the fact that Products are
more like genetics than environment.  A product (currently)
affects an entire site, not just a particular part of a site.

Having said that, I can imagine having products in the future
that affect only part of a site.  Functionally, this would be
useful, however, logistically, it is rather complicated.

Products are about packinging and defining constructors.

Classes are about defining behavior.

When you want to package a bunch of things 
up or define how things get created, use a product.

When you want to define a new kind of thing, use a class.
