There are several ways to deal with this.
If you have an idol you can hire people to port in and either, palibash it or give/trade ram materials to you. And possibly help you ram it aswell. (This is risky, cause getting the wrong people and they might just kill you and take all your stuffs)
If you dont have idol, but know the cordinates for your place, you can hire people to help you palibash it or ram it from the outside. (This is risky, cause getting the wrong people and they might just kill you and take all your stuffs again)
If you declaim the place, and instantly build a new claim stake, and claim the whole thing. Part from the Pieces you want removed, which will slowly decay. (But might be repaired by anyone who passes by. Good chance the guy who did this in the first place will repair it if he lives close to you.)
If you have a coop, and got seeds aswell as breeding chicken pair, you might aswell just wait for them to multiply enough so you can make your own ram in time. (You can drive the ram trough palisade gates. Also, if you drop chicks on the ground and then punch them, it will leave a dead chicken on the ground. Allowing you to pick them up and butcher for bones.)
And you can also get enough strength, and break your hf. And then log out, and have an alt place something where you logged off. And then select to spawn somewhere in the wilderness, and either work your way back to your base, or build a new one.
Or simply just make a new character and get a fresh start.
