I can’t offer any perspective on the business-owner side of things but I can give you one from where I sit as a hobby-bladesmith.
If I were to have to isolate, I can think of no better place than my workshop so will hopefully get some things done. I may even be able to build up some stock as, though people are hanging on to their money at the moment, that money will hopefully be available after this to spend on some nice items (plus the money people will have available from not having to buy all the things they stockpiled ). Of course there will be a dip also due to people not getting money in during this time so market recovery is likely to be a slow process. Obviously one should try not to flush the market with under-priced items when it does pick up but needs must.
I think your idea about online demonstrations, hammer-ins, etc sounds great. With reduced social contact we will have to turn to the web to get our fix and though this isn’t as much fun as being there, it is better than nothing. Potentially buying the edited video afterwards could give you (the presenter) another stream of income (though I know nothing of this sector).
Every challenge is a new opportunity if you don’t sit and stare at what you lost. By their very nature challenges aren’t easy but isn’t facing and finding creative ways to overcome challenges what we do as bladesmiths?
