Unschooling: experimental or experiential?

A few posts ago, I was wondering why so many people call unschooling an experiment. Someone in the comment section asked me to explain why I didn't like calling unschooling an experiment. I guess I didn't do a good job the first time so I'll give it another go.

To me unschooling is less of an experiment; more of an experience. I like to think of unschooling as experienced- based learning as in a collecting of, a conscientious bringing together of action, observation, deliberation, reflection, immersion of self in the flow of life.
Of course, along with this comes experiment. One experiments with ideas. Unschooling is not an idea. Unschooling is a way of life; a philosophy of life. It embraces the experiment; it is not the experiment.
This is how we humans attain adulthood—by the experiences we live through.

Rather than counting our years by the measure of what grade we are in as school does and waiting until we have worked through all the grades before set free,we can begin to live, unschooling demands experience now.
I understand how unschooling can be viewed as experiment—the 'what we don't know' as contrasted with what we do know: school. But I find that the term when used on unschooling tends to cast unschooling into a light that makes it (unschooling) seem like something uncertain.

That's what I don't like. Unschooling as an experiment conveys an idea that I am uneasy with—the idea that unschooling is something that careless or neglectful parents might do. People who do it are the opposite. They wish to conserve the natural traits of their children; creativity,curiosity, self-directedness. They are not willing to toss that all into the school pot—which to my mind, experiments largely with these natural qualities—often to the detriment of the child. School is the largest experiment devised for young humans.
Unschooling families wish to preserve family and community. The great experiment that separates kids from adults for the most part of their childhood is not one they wish to support. Unschooling refuses to let children be the guinea pigs in the school laboratory.
Unschooling as experiment suggests that the parents are experimenting on their children. This is not the case. Instead the child  leads with his interest; the parent supports the interests. The parent facilitates exposes, the child follows.  At its best, usnchooling is a partnership in learning and living.
