For this type of setup, you typically just bring a regular monitor that stays at the location your frequent.
Thats why I said its really for when you are back and forth between 2 locations not super frequently/doesnt work for frequent travellers do different places.
If you need a portable monitor for your usecase, I’d guess that a SFF PC might not be the better pick vs a gaming laptop for that user.
Thats in an ideal world, but its not practical for the US in particular because their system only allows for 2 parties.
In fact, many systems boil down to that due to first past the post forcing people to vote strategically instead of for the party that best represents them.
In reality, people have to vote strategically and then use internal party politics such as primaries to shift the party to a more progressive place.
Threatening to make them lose only means the worse party comes into power and rachets everything backwards far more than leaving them in place.
