I have seen standing hooks - I think they're called shepherds hooks? - and have considered getting one for similar reasons, I'm not so much worried about the structural capabilities as much as I know I will want to change the location lol.

I am in Phoenix and have been wanting it moreso because makes sense for our landscaping - a work in progress but basic desert xeriscape - the zone climate etc makes it easy to work with, esp as i can use the environment (big rocks etc) to keep things weighed down if need be.
