Those were issues of infrastructure which weren't built out, but could be built out.
Are you planning on refueling the boom mid-air at supersonic speeds?
Tesla also took an approach that analysts who clearly weren't "car guys" weren't expecting: mainly creating something with massive HP and TQ. Previous electric cars had yawn-inducing performance. Someone buying a 5-series probably at least partially bought it for the performance, when they got behind the wheel of a model S it was like getting behind the wheel of a modified M5.
Boom isn't bringing anything new to the table to solve the issues people have listed. Tesla had a plan to solve those issues from the get-go.
Boom is bringing to the table that the technology has advenced in the last 50 years and even the Concorde might have succeeded, if a second iteration had made it to the market. Also, partially the Concorde failed because Boeing opposed it. They were working on their own supersonic plane but were a few years behind. Unfortunately, they were so successful in blocking the Concorde, that their own project failed as the market had become convinced that supersonic flight doesn't work out.
