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.
Your proposal is not new and this issue has been discussed many times, but it is better to repeat this several times in order to avoid unexpected losses in the future.
Paper is a fragile carrier of information and you can't argue here. Then maybe use other, more reliable ones? Metal, plastic. Plastic? I don't remember anyone suggesting this option. Sure, it's not the best way, but it might be better than paper. Although it can't withstand fire in the same way, neither the tears of bitcoiners nor water can spoil the text. Easy to apply: heat iron dies and press against a piece of plastic.
Two copies may not be enough. At a minimum, you should start with 3 pieces.
I see it like this: 1 carrier of seed phrases on paper in easy accessibility, which is not a pity to lose. 2 media on plastic, for example, stored more securely. 3 carrier - on metal and hidden in the most reliable way in the most inaccessible place and being the very last reserve.
