Forty years ago(!), a good buddy nailed up four permanent stands, with my permission, to trees in the best locations on our farm while I was away at college.
Within a few years, each of those trees died. Each has long fallen over, but no other tree in each area is positioned to take advantage of what was an amazing hunting site.
25 years ago, a kid nailed up a permanent stands to one of my remaining favorite trees WITHOUT permission. That tree is dead and gone, too.
Perhaps this does not always happen, but every permanent stand I have ever been around has meant the end of the tree. Perhaps that won't matter if you own the land and have a number of other options, but I regret that they ever happened on our place.
I have gone to only ladder stands due to age creeping along and medical trouble... but also to keep my trees alive.
