It is certainly understandable that courts might need to temporarily pause certain operations to ensure the safety of all participants. But you likewise have every right to expect your Constitutionally-guaranteed jury and other rights to be treated as "essential".
You may be interested to know that my extensive research suggests that the legal processes being treated as "essential" are those that are most easily modified to continue with social distancing. As you might imagine, trial by jury is not one of those.
Almost uniformly, courts seem not to have given a moment's thought to how to fulfill your essential jury rights during a pandemic—despite having ample time to make a plan since the SARS virus was identified in 2002, the 2009 H1N1 pandemic, and other harbingers of the current situation.
Rather, virtually every court seems to be starting from zero in trying to devise ways to get trials by jury up and running again, in light of safety, fairness, and other concerns.
This may not surprise you. One might suspect that many government officials—who had already almost entirely replaced trial by jury with coerced plea bargains and bench trials—are salivating at this unique opportunity to put the last nail or two in the coffin of trial by jury before burying it completely.
