That rings extremely true to me, the issue you run into is that liberals and conservatives don't believe the government has any role in the commercial relationship between adults. This means any limits you want to impose on the "free market" has to be directed at protecting children, since those are the only people you're allowed to protect.

We already have many laws to safeguard children, the problems being that children have been taught to self declare as adults, and parents can't stop that without some help from the technology.
