Ah this old thing... Yeah it's a difficult thing to do for those uninterested and even those interested that don't want to be affiliated with it. It probably makes more sense to find a way to at least keep the btc circulating somehow. It might also be possible to. Leave funds on an exchange or make it so tfunds can be transferred to an exchange by broadcasting a transaction which your family might then have access to and just have to click "sell".
Only if that exchange still exists after I pass though! Most exchanges seem to refresh wallets often enough, it'd be another hell to fix it with customer support. As long as they're somehow with the keys I suppose they could always seek help from someone. Thinking of making all KINDs of instructions or really just finding a way to put it in a will and update it as much as possible.
