Carbon copies is very much a goal.
Grand expenses to change the park could easily have been put towards reconfiguring the land to better work with more than ample space outside the park. But such a move doesn't radically alter the park, a common goal throughout the project's development.
I'm not sure if you are privy to something I am not? Why do you assume the goal is to (and I am paraphrasing) destroy a part of Disneyland to suit Iger's ego? Secondly, even if the goal is cloning, DHS is very flexible in terms of space, DL is very much dictating layout by having to work around so many more legacy obstacles.
The park is not really being radically altered. They were going to radically alter the park by ripping out the subs/autotopia. They were going to less dramatically alter the park by removing a land people generally don't care about (Toon town) to get at further backstage facilities.
Now they are least altering the park by spending a ton of money to reconfigure (and
not remove) legacy attractions so they can finally access a large chunk of land beyond the berm, expand the park's acreage and fix a lot of their guest flow issues such as the dead end that is Critter Country. All while altering, outside of Disney fandom, very little anyone would remotely notice.
Would you prefer that they instead roughly halve the size of the proposed land and avoid any reconfiguration? Which would also require a bottle-necked single entry point reminiscent of Toon Town. Because that is what it would require. You can't just spend more money on 8 acres to make it feel like 14. If they are going to bother doing it at all they had to do it big to accommodate the hordes.
I totally respect the opinion that ROA is something that should just not be messed with and people's attachments to all areas of Disneyland, but it's a poor argument that they aren't going well out of their way to protect legacy Disneyland to gather together enough space for an ambitious project.
People have very diverse and strong opinions on this matter obviously, but I get this sentiment that there is a superiority when it comes to ROA. It shouldn't be the intellectual preference to think that if you disagree with the expansion you are beyond those who like the plans.
