No what is unsafe is LEAVING a rope or wire wrapped tight around the tree
from one year to the next.

Obviously. But, I assume most people aren't going to hang and UNhang their
hammock every day. Life's complicated enough.


It is safer than trusting a hook.

There are 2 hooks in my sycamore that've been supporting a rope swing for 13
years so far. Two big, fat self-tapping hooks, one adjacent to the other in
case one fails. So, saying they're unsafe is just a generalization, like
saying "rope's not safe for tying up a boat". Depends on the hook, the rope,
the knots, etc.
