If you do nothing at all, your funds will never move after you die. In reality, you're actually taking those unspent outputs out of circulation forever, so you'll be responsible for a tiny increase in bitcoin price... Less supply + equal demand should increase the price 
In my case: I have one daughter. She knows where to find my hardware wallets, she knows the pincode and i've taught her the basics. After I die, she'll be able to spend everything I held my whole life. I tried to make things as simple as possible for her: no hidden messages, no extra encryption, no ssss, just a hardware wallet and the proper gui... Making her jump over hurdles will only decrease the odds she'll actually be able to spend my funds, and i'd rather have her rob me wile i'm still alive than increase the odds she won't be able to spend my holdings after i die.
Yeah, that same goes for me I would rather to rob by someone whom I can entrust my Bitcoin stash to than it to go into waste for nothing. I mean, all of my years of earning and procuring Bitcoin would be just in vain if I coudn't even use it so better if someone on my family would have it and make them use of it. Though I haven't share my seed yet but once they got accessed on my password storage it wouldn't be that difficult because everything they should know was in there. In my case: I have one daughter.
