You do know, having played the game, that in some situations (standing stones and abandoned farms) the boars found there are tethered to those locations so even if you are able to tame and get them to your base they will, if they escape, go back to where you found them.

Emphasis added. Yeah this is the Iron Gate acknowledged bug OP is talking about.[valheimbugs.featureupvote.com] These things freak out and keep trying to return no matter what, sometimes not even eating or breeding - it's not just if they get loose. And although OP went way off the rails and apparently got banned already I do sympathise that it's quite frustrating.
