Structure insurance

With pvp corp’s wardecking like crazy now, picking on the little guys…
We find more and more pvp corps, ransoming small corps for ridiculous fees or they threaten to destroy your assets.
why can’t we have insurance for our structures? it can be the same principle as with ships with multiple levels of coverage to suite your wallet, same 3 month plans. so when you get wardecked & loose your structure(s), it’s not a complete 100% loss, go back to start & do it all over again from scratch.
