I recall an interview with Jon from a few months ago where he was asked about getting back on the road and his answer was (I'm paraphrasing) he would love to get back on the road in 2021, but it will "also have to make sense from the business side". I think what he meant was that it's not just about COVID-19, even when people return to normal lives, there will be a lot of immediate supply on the live entertainment market given how most artists have waited 2 years to tour and make money and if you can afford it, it might make more sense to wait another year for a big tour so that there's less competition.
