It would of perhaps been an easier sell if we could of built it much closer to the WCML and told people, look this is to get rid of those horrible fast trains that wizz though your local station at 125mph.We'll use the space for more services so your commute to London from say Leighton buzzard is faster and less busy.
Knocking down half the towns that the WCML runs through to build more tracks carrying trains that aren't going to stop there would be neither easier nor cheaper than HS2.
The whole way HS2 is designed is to maximally reduce the amount of fast trains going north south on the existing network. Leading to a massive capacity upgrade on the existing lines. You can still run some express lines but likely much more lines that stop at more station, making it fast for you to go to next HS2 stop and from there to the further distance destination.
HS2 connection to Leeds was designed to help the ECML, the whole HS2 system was designed by experts to help with WCML and ECML.
Of course now that the former car brained fucking moron of a prime minister in his last attempt to safe himself canceled most of HS2 all those benefits are gone. And labor is to cowardly and ignorant to bring it back.
You analysis is very narrow and only considered the benefits to a certain set of people.
HS2 actually follows reasonably closely to the old GCML. And for the same reason, its the best route to build a fast rail-line along.
I think your proposal complete ignores the additional cost of such a route change. And the cost alone, aside from anything else would make it unreasonable.
Many things go into selecting a route and in most cases where I think they made the wrong choice its usually because of cost concerns, like not building the needed tunnels into cities.
The reason HS2 route cost so much money is because so much is tunneled. Why is so much tunnelled? Because rich people live there and won't accept a blot on the landscape, partially because they don't see a personal benefit.
If you can remove the tunnels it doesn't really matter that the route is slightly longer or has slowly less optimal geometry.
And you don't get magically rid of all issues with people complaining, because guess what, other people live on that other imaginary route that lives in your head, and they would demand tunnels too.
And its really the politicians fault, a few people who don't like the look of the train should not have the power to stop it, specially not in a place as centralized as England.
