The operational argument is very persuasive. A 30 minute interval service is currently possible with just one train. Very economic. Access to Hayle by road is hardly difficult though, straight in along the causeway from the A30 roundabout, and parking could be improved. Something really needs to be done about Hayle's atrocious train service which has some huge gaps. It's the only station in the far west of the county that gets such a rubbish service. Long distance trains all typically call at Redruth, Camborne and St Erth but only a few also call at Hayle. As once you're this far west long distance trains are providing much of the local service, this leaves Hayle with the short straw, not because it's an insignificant stop or because its station is poorly sited (it's extremely well sited in fact) but simply because it's too close to the next station which happens to be the junction for St Ives. Even many local trains from Bristol or Exeter miss out Hayle especially in that infamous three hour gap in the evening. If the branch had been built from Hayle in the first place, I would not have thought a station at St Erth would have survived the Beeching era. Maybe it would not even have been built.
