I 100% agree with you. It is unfortunately all tradeoffs. Let me play the devil's advocate though (for the Op's sake):
If you set up a multisig and it works for years and years but is ultimately too complicated for heirs and family to use after we are all gone... then what was the point? Ya sure it's secure - but if it's too complicated for recovery then what was the point?
Yup, absolutely agree.
If your setup is too complicated for you and/or your heirs to use, it is useless. Multisig, IMO, is not actually much more complicated than single sig.
Let's run through a 2 of 3 multisig example where your child has one key, you have one key and your lawyer (or safe deposit box) has one key. You pass away and you have left instructions in your will for your child to open the bitcoin envelope you left them since you've passed. Inside the envelope are:
  1. A set of instructions
  2. A written and metal backup of one set of seed words
  3. A backup (physical piece of paper printed pdf and on a microSD card) of the public keys (this pdf and electronic backup are created by your wallet software like sparrow)
The instructions (#1 above) are fairly straightforward. Essentially your heir must:
  1. Acquire the second envelope from either the lawyer/safe deposit box or from your home
  2. On a (preferably new/clean) laptop download sparrow wallet
  3. Using the microSD card (or the backup physical paper) load the saved wallet
  4. Use the sparrow interface to attempt to send the bitcoin if desired - provide links to good resources/videos on how to spend such as one from BTC Sessions (https://www.youtube.com/watch?v=qJ_SpQX_YKw)
I am not saying this is 'easy' per say. But I also don't think it is overly challenging, especially considering your children will likely be more technically proficient than you are. Additionally, I believe you could point your heirs in the direction of solid bitcoin companies that provide consulting help and I imagine for a fee they would help the heir with the recovery process once they have the requisite keys in hand. I imagine folks like these could be helpful if they need some handholding:
Probably several bitcoin focused lawyers that you could reach out to as well who could help in the process...

Thank you for your post.
Yes Bitcoin and software security in general... is always a moving target. There's good and there's even really good, but there's nothing that's perfect.
In my opinion Bitcoin can't be and doesn't need to be perfect, it just needs to be better than everything else and it is. And the way to achieve that is education salutes
