He's a baby dog, still, and this really isn't unusual behavior, especially for a Golden! They are retrievers, and they like to use their mouths to explore and, well, chew!
He's a baby and really does not know any better. You must prevent him from accessing inappropriate items when you cannot supervise. So, dog-proof a room or invest in a crate. When you cannot supervise, he is in that dog-proofed room or in his crate. He is a young dog and still needs to learn that when you are not around, he needs to chill out. The crate helps achieve that. If you choose to do the dog-proofed room, you must make sure there is NOTHING he can get into. No wires, no objects within reach, nothing. Just his appropriate toys and perhaps bedding if he can be trusted not to chew that. If he's the house-eating type, then a crate is once again going to be your best option.
I would not recommend leaving a dog out in the yard all by himself, especially not tethered. Out in the yard, there is the risk of him digging out and escaping or having someone steal him. Goldens are popular dogs and someone may covet him! He may also bark incessantly, which will annoy your neighbors. Tethered, there's the risk of him becoming tangled in the leash or possibly strangling himself. A crate is the safest option.
