So do you remember the terrible earthquake and collapse that happened in Türkiye and do you think there will be any technology advanced enough to know the full extent of mother nature's fury? It seems like you are trying to blame the government for the natural disasters caused by mother nature.
As I understand what the OP is trying to say, the OP is pointing out the disadvantages when we use steel plates to store seed phrase and they are hidden in the house or backyard. That shows that every method has its drawbacks and nothing is absolutely safe.
Your bracelet looks beautiful and quite secretive, but can you guarantee that if you encounter a strong impact it will not fall out of your hand? Don't be too subjective, everything has its risks.
An earthquake is a completely different matter compared to a flood because your house can actually collapse completely. The main difference is where you live because if you have you own private house then you should still be able to find your steel plate; if you live in an apartment complex, maybe a big one, and it collapses then there would be so much debris that it becomes almost impossible to find it. Maybe a solution could be to place it inside some kind of strongbox colored/painted with some very bright color, like they do with plane's black boxes.
