2) Access: But what happens if you travel to a foreighn country and get arrested and need access to your Bitcoin funds to pay for a good lawyer?

How does it help that you have the seed phrase hidden at home???
Maybe worth to have set up an online option to access your seed phrase, at least then you have a chance to use your Bitcoins .....
You can have some funds on your hardware wallet or software wallet that you'd use while on a vacation or business trip to a foreign country. You don't need to be carrying your seed phrase around and I strongly kick against it. Having your seed phrase somewhere very safe doesn't stop you from accessing and spending your funds. So if you find yourself in some kind of trouble and you need to access your Bitcoin to pay for the services of a lawyer, you can still do that.
