Flying seems in this article to forget that one country in the world already has made the transition to unleaded AVGAS and that happened 30 years ago. Flying also seems to forget that
there is an unleaded AVGAS now in production for 20 years that has engine manufacturers approval covering > 90 % of the entire world piston aircraft fleet.
Of course this fuel also has full approvals from the European FAA, The EASA.

This fuel also has flown for millions of flight hours in thousands and thousands of aircraft
in all possible weather conditions during these decades.

Things also happen outside the US -- Wellcome to Sweden where you will find unleaded
AVGAS at almost every GA-airport.
