Well you know best, and so much depends on your situation.
If there are a lot of coons ~ and scarce food sources for them ~ and taking you on isn't scary to them, then building a new house may be the solution. I just have a personality that wants to retrained any wildlife which wants to have a go at me or my animals, but that's just me.
I don't even get raccoons around my place in the winter, but in the summer I hear them and run out in the night picking up my high power jet hose on the way and blast them out of my neighbors trees. I've never had one even test out my yard ~wicked grin~. A skunk did one year and we blasted him so good, right in the pie hole, he's never been back since. But then, they all have easier pickings in other yards around here so they move on. May not be the case in your situation. But if you can make your situation just not worth it for marauding animals they will get the message.
They train black bears in areas where houses butt up to national forest by having one person chase the bear until it takes to a tree and then the person throws rocks, yells, bangs pans against the tree just putting the fear of God into that bear. Since they have started this program they have had no reports of bear troubles, it's just not worth it for the bears.
When it comes to livestock I do like dogs as backup when detouring other dogs, raccoons and opossums
