Not "ramblings" from the OP, but a range of highly relevant points. Let's not change the subject on to 3 Peakers, appallingly though some behave.
Many of the points made by the OP (some reinforced by Bob) form the advice I've given to contenders over the last 12 years.
Keep the challenge simple. Prepare well. Have the necessary skills. Keep the numbers down. Behave properly. Respect the landscape. Respect those who live and work there.
My friend Meghan Hicks completed a successful round in May. Part of her write up raises a series of points about over-use and environmental ethics. It's deeply refreshing to see someone reflecting on what they saw in the landscape and worrying about the effect of their actions.

Meghan was led down the Parachute descent one evening. We discussed the route at length. She doesn't refer to this but she all but dismissed using that descent exclusively for environmental reasons. The steepness and looseness of the route, in her view, will with over-use result in major erosion and scarring. Meghan worked for years in the US National Oark Service in some honeypot locations.
For me, it's time to put the landscape first and foster a culture for this challenge that thinks much harder about the consequences of our collective actions and changes the way we do things.
