You have an expensive aircraft very well fitted.
Then there are those out there without $15-20K GPS who are reliant on their VOR or ADF for some of their operations in their $75K aircraft. At prsent the Albury NDB is a hot spot of debate re retention for such people.
Likewise for VOR.
The "unmentionable" provided an incentive to equip with 146 and escalate the demise of the navaids. Even so, the backup network is still quite substantial remembering that should Bing's whizzer ever turn off GPS there is a need to safeguard those very RPT you mention until they land.
But, it's all at a cost. And, likewise VHF coverage. However, VHF won't get you on the ground in IMC.
Even funnier, even a faulty data card can crash that sole means GPS which you only need one of. If you are 'in the soup', in the soup, with your one GPS blank, the good old antique NDB and VOR might seem good friends indeed
