|Even clone troopers need a little recognition...|
However, one might think that the government wouldn't have to honor its clones, who are effectively property. The presence of the statue is an interesting indication that Palpatine's government feels it has to to at least put on a public display of honoring the clones.
The question is whether the statue is for the clones or for the public. Clones don't have families, so it's not like there are families demanding a public memorial. So, it seems like the statue is part of Palpatine's attempt to solidify the loyalty of the clones.
It's certainly an interesting time in the politics of the Republic!
