Yes
I think they should be moved, after all some people paid good money, in good faith, so that they would have a "legacy" on display for years to come and it would be a flat rip off to them if Disney just got rid of them. Having said that, the current location on the entry esplanade of Epcot's future world is horrible, nothing says a bright, shiny, wonderful future like a bunch of dark, granite monuments that look an awful lot like head stones. I have rumors that some people have even go so far as to deposit their deceased relatives ashes on or around the monuments.... Yuck!
Perhaps they could create a "granite garden" along the path from Epcot to Disney-MGM. Then not only would the legacy that people paid for still be there, the purchasers would be able to visit without paying park admissions.
At the risk of really being morbid, Disney could take it one step further and sanction people's ashes being left there for those fans that just couldn't get enough whilst they were alive. Of course that is assuming the Disney could legally do such things AND equally importantly they could assign a plot of land that really would be left for that purpose for ever. Sorry if this last paragraph offends or disgusts anyone.
