A possibly unpopular opinion of mine is that I am against the idea of listing amusement rides or mandating their permanent preservation.
Don't get me wrong, I do understand the sentiment behind it, and I am all for the preservation of iconic or significant rides where it is feasible and in the public interest.
However, I think that the idea of listing rides has a couple of flaws.
One principle flaw is that listing a ride (under the UK building listing system) merely mandates that the park keep it standing and don't majorly alter it. That does not force them to operate it. That to me seems to make the exercise of listing a bit pointless; surely the intent behind it is to keep a ride operating, so if the park doesn't operate it, that defeats the object of the listing, does it not?
The other principle flaw is that listing a ride could mean that that ride eventually stands in the way of progress and becomes a huge burden for the park. What if a ride that is listed becomes unfeasible to operate for whatever reason? At that point, you've hit a complete lose-lose situation for all parties. The folks wanting the ride listed lose because the ride can't feasibly operate. The park lose because the ride can't be removed to make way for something new due to the listing, meaning that the ride just sits there SBNO and becomes a massive millstone around the park's neck.
A ride that the park are obligated to maintain and keep standing that they can't feasibly operate is a complete white elephant that does nobody any good; the folks wanting the ride listed can't ride it, and the park can't replace it, so nobody wins. That is what I fear that listing rides could lead to in the long term.
