Lessons( 1) Do not keep your seed phrase in a particular place (2) Always check your seed phrase to be sure it is intact (3) Be sure you alone have access where your seed phrase is kept.
Conclusion: Knowing too well that keeping the seed phrase and other account related information of a user private are some ways to ensure adequate security, I think we need to do a constant check on our seed phrase so that we don't end up losing it.
I rarely check it unless I really need it, and I feel safe enough with the way I store my seed phrases that I don't feel the need to check it often, and store it in several different places but still only I know where it is stored.
However, I agree that we are the only who have access to the seed phrase storage, unless there is a family we can trust to anticipate when something unexpected happens.
It's possible to avoid things like what you experienced, for example being erased or lost by using material that won't be erased, such as a stainless steel plate to record the seed phrase, which means we have to be willing to spend more for the security of our wallet.
