I feel extremely sorry for the workforce and their families but if a business is not profitable it has to go.
I have no desire to support another failing industry whatever the circumstances of the demise.
Consider this scenario:
1. China uses its massive production capacity to dump steel onto European markets at less than production price
2. European steel industries cannot make a profit due to high fixed costs
3. Governments refuse to support the industries
4. Industries close down
5. China stops dumping cheap steel and puts the price up
7. We can't restart the steel industries as the capital cost is too high
Of course, China is a responsible and trustworthy country and wouldn't even remotely consider such a strategy.
