Courtesy is important and the AMR(Adirondack Mountain Reserve/Ausable Club) did safeguard all that area including their ownership of 13 of the ADK HPs for about a century.
For quite some time, NYS was negotiating with the AMR about either buying or getting an easement to the 13 high peak summits that the AMR owned since the turn of the last century. New York State did not feel that it was in the public's interest for a private club to own the summits of so many peaks. They tried everything, including a threat of eminent domain. Finally, in the 1980's NYS threatened to tax the land as real estate development property. The AMR, facing a forced a sale of some of the land or being driven into tax court, sold the land above 2,500' to NYS. In addition there were provisions for permanent hiking easements on certain trails, on the Lake Road, up to the new state land boundry. There are restrictions: NO dogs, hunting or camping on or THRU the AMR easement. No hiking on the private trails around the Upper Lake. This is for the privacy of the campers there and the security of the camps back in their.
Courtesy is a good thing. On the other hand, the easement is the easement and it does not have a "courtesy clause". It would be a shame for hikers to have confrontations with the AMR members who've taken such good care of the land over the years.
Continued access to AMR land, though, is not reliant on good will.
