Hear me out guys.
Paper can be really fragile, and all it takes is a tear or water spill or defacing to deny you access to your BTC forever.
So, you should make a second copy of your seed phrase that is identical to the first, and store it on a different place from the first seed so that they both cannot go down together except in extreme circumstances like a natural disaster.
Making more copies is risky too. A burglar might steal your home copy while you are not home... You may protect yourself from a natural disaster but then there will be other risks... On the other hand having only one copy is also risky because anything can happen to it. There isn't a foolproof easy solution to this problem imo. Physical paper wallets have their own risks, memorizing the seed words is also dangerous because dementia is a bitch... computers can get broken or get hacked if they are connected to the internet. Should you make 2 copies of your priv keys? Maybe. But I know for sure, you shouldn't make more than 2.
