This is a classic contrast between Apollonian and Dionysian modalities. If you don't like classic analogies, try chaos theory and biology (since we're gardening):
The human body has both the hard bones (order, Apollo) and the soft, flexible muscles and nerves (the loose, Dionysus). You couldn't escape a wolf with just one or the other.
There are no organisms, let alone networks of organisms, that operate with rigid systems alone. Some, like jellyfish, are fairly loose but even they have tensile strength.
If you get rid of your experimenters, your creative community, you lose your adaptability.
You also have no vision and no fun. Gotta embrace both parts of the social continuum.
Besides, isn't the looming danger of the Trumpians that they have simplistic, rigid, fascist tendencies?
We need to go high, as Obama said, and embrace the diverse range of talents and modalities of the social organism.
We should embrace all the different suggestions for dealing with food distrubution and homelessness. We should also be more insightful about how an interesting action, such as guerilla gardening, can draw people into the larger urban gardening movement.
