I appreciate this is difficult for you to fathom but quite a lot of people are more concerned with the direction their country is heading in over their personal economic considerations. It is actually possible to put aside immediate financial concerns and be reasonably objective. For example, most scientists are more concerned with science than they are with getting rich. Most professors are more concerned with education than they are with getting rich.
I was well hedged and did well out of Brexit, at least in GBP - though those pounds are now worth a lot less. I'd quite happily give it back in an instant to remain.
