That's not the most important thing by far, nor do I even think that statement is true.  This outbreak may push the world toward being more cashless, but I don't think bitcoin is necessarily going to be a beneficiary of that.  Not unless more merchants start accepting it, and even then there's the problem of how bitcoin offers the average person an advantage over using a debit card or their smartphone when making payments--and that's been an issue right from the start.

This epidemic might be an eye-opener to the current population of humans alive at present, but memories are short.  Very few living folks remember the flu pandemic of 1918, which was much worse than COVID-19 in terms of lethality.  I'm reasonably confident that a few generations from now everyone will have forgotten all about this, and the world will have gone back to what it was before in terms of forgetting to wash your hands and staying six feet away from everyone else.  People just don't learn.
