Re: Bitcoin would have averted this painful loss, shame on fiat
The traditional banking system is not perfect (note, before the advent of bitcoin you all silently used this system) and the world has not abandoned this system yet. But bitcoin too has its shortcomings. You somehow quickly forgot about last year (or so) of BTC-mempool load and the resulting transaction delays and high fees. You should not overestimate bitcoin, as well as underestimate fiat, but rather take a realistic look at existing financial instruments and use the advantages of this (having leveled out the disadvantages by using alternative solutions).
I often see people totally discrediting the fiat currency or the bank system I know we all must have had a very terrible experience from this traditional banks but I will say they have some times I prefer to use them over bitcoin as at then it will be easier and that’s why we say bitcoin is an alternative to it and not to take over from it, although bitcoin edges over it way more to me.
But regarding this particular Situation bitcoin can never be like this, this a situation where the bank charges the fees without his prior knowledge which is very wrong. On bitcoin network you fees are what you set by yourself when you see excessive fees then it is usually the human error of the sender, no miner can take more than your fee. Look at the the price example you brought it was the sender that used 0.7bitcoin as fees
If you want your transfer on Bitcoin to be finished with the same speed as wire transfer, you will have to pay similar amount in network fees 
Just look at the high fees people are paying:

€100 is the fee charged there, this is not usually common with bitcoin although on some occasions when there is congestion we get this kind of fees but not right now. A $1 will get your confirmation into the next block if it is one input one output transaction
