I think your No.1 does not go far enough.

The general malaise in recognizing how important the growth of the leisure industry to modern day economics has not seeped into the political system. The Rights of Way network should be allowed to alter, so that it links into the public transport system. In fact many lostways are old pedestrian routes to defunct stations (Beeching's axed rail lines).
A point that seems to have been left out of the 'Stepping forward' initiative, is the value of these old ways. If you a have a route from one direction and another from the other side of the line, then there is a longer route, often across countryside, that is lost to the network.
This leads to a thought that there was a civil understanding that allowed footpaths to develop for this very purpose and this has been lost by the current thinking of a fixed rights of way system.A Prime example of this is in the 11 square mile area without RoWs in Herefordshire adjacent to Harry Cotterill's estate, the landowner, who was President of the CLA, when they published a policy on access and around the time that much of the negotiation was taking place.Now this links into the development of Health and Safety legislation, landowners should not allowed be exemption, by creating risk in denying reasonable access, to a recognizable destination.
Astaman's post is relevant, but the means of withholding SFS payments for non- compliance is there to be used, the onus should be placed on the landowner not the farmer, in this way the penalty falls on the part of the business that is responsible for land management not food production. It is ironic that the area of land that is used for public access is taken off the acreage SFS are payed out on, that acreage has an economic force both direct and indirect, this benefit to the rural community in income is substantial. The loss is born by other rural enterprises and not the landowner, who denies access.
A recognition from landowners that their occupation of our countryside has an impact on all of us. Perhaps they should have a code of conduct that reflects this, as 99.9% of us observe the countryside code and perhaps those that don't would be better behaved if the example was set from their side.
