Travelers/Nomads - Security Protocols? Password/Seed phrase backup?

What is the complete list of international travel security protocols for traders/hodlers?

Let's say worst case scenario everything is on your Ledger, and you lose your phone, Ledger, Yubikey, laptop, everything due to luggage or theft or whatever.

You have to start from scratch. What do you do? Assume you don't have a trusted party to leave info with, you are on your own, security wise, and don't have a permanent home to store this stuff.

With regards to trading, I can see using just your phone to access exchanges, with phone 6 digit pin (and not biometrics) unlock. That gets old quick. Do you use your laptop? Seems less secure to someone getting their hands on it. Say you're at the beach, going swimming or surfing. Or just heading out for the day. Hotels rooms are never secure, let alone bungalows.

How do you store passwords?

What do you do with your Ledger/Trezor if you are going swimming or surfing or whatever?

How do you store Yubikey? (neck lanyard? what about water activities?)

Have your devices attracted attention in customs in foreign countries?

Losing access to your Ledger could mean losing your life finances permanently for some. How do you store your 24 word seedphrase backup in case Ledger goes missing? This seems like the most risky thing. I could see using manual encryption like using someone's name (ACE FREHLEY), offset the bip39 word by the numerical value of each letter. So if it's ACE (letters #1,3,5), you would write down the 4 digit bip number that is "1 ahead of your actual bip number", then "3 ahead of your actual bip number"? What is the best manual encryption method? You still risk losing that written record. Obviously Rule#1 is your seed phrase NEVER touches the internet or digital file. EVER.

Seems like there are a lot of catch 22's. Is there an encryption method that is safe enough to email to your self so you can never lose your finances? How do you then make sure you have a bombproof email, that you can never lose or get hacked, and how do you store your password to that? Maybe 2 emails with 12 words in each, and similar passwords. It seems like memorizing an email may be the key to this if things are encrypted properly? That is still extremely risky though if you lose access to your email somehow. It doesn't seem like there is an actual safe way to do any of this other than an ecrypted tatoo which doesn't seem optimal?

How are you securing yourself from losing everything? Thanks.
