The problem is that there is no consensus on the correct way to regulate these kinds of interactions yet. When we try to work out what a reasonable way to regulate something new is, we usually do so by analogy to other things that we already know how to regulate. That way we can make a whole bunch of analogies with various current situations and try to work out which one is the best analogy in the relevant aspects so we can come up with a good starting point for regulation.

This doesn't always work (particularly not for truly disruptive technical or social changes), but it's a pretty good way of doing it.
