Nail on head there!!

There are various competing interests ;

Obviously the fans
The taxpayer (the Government)
The riders/teams
The non biking residents/TT haters
Businesses which make a living from it

The fans and their contribution to the economy are the driver for everything. If they don't come, there's nothing for anyone else apart from the haters.

It still surprises me that the organisers don't base their thinking on this premise.
