This happened often before right? Banks that act like this will lose their customers and banks that are bitcoin friendly will gain. They will learn their lesson over time. Banks that adapt will flourish and banks that reject will go down.
Besides that it is a proof that you don't own your own money when it is in the bank! They proof how useful BTC is, isn't it hilarious?
Perfectly summed up, but let's hope that we won't need big banks anymore in near future. Upvoted.
