I do not really advocate for builder rights, as they are just little bits of code. However, I do like that idea of no gems for a builder, but a happiness level. I'm not sure how it would affect the game, however.
Also, I think builders are actually made of condensed gems

If you think about it, everything in the game except for the villagers and the decorations are made of a resource.
i.e. Troops are bags of elixir in different shapes, that can move about, and are put together by builders. Thats why at the end of a battle, all the troops go POOF into drops of elixir. Same goes for DE troops.
Defenses and walls are made of gold, hammered into some shape that responds to different situations like battles.
So, as builders are bought by gems, wouldn't it make sense that they are gems?
Also, I notice you are not advocating for the rights of troops
If we were to get into that, why do the poor barbarians go into battle with no armor?
Perhaps not the best idea to change the builder system, but a new way to get builders is an option, but I think i like to buy my builders with gems.
And I don't want to hear protestations against this and you trying to guilt me into supporting builders rights, because thats a heinous crime, using someones goodwill to harm them.
I will consider a valid reason, however. Just don't use guilt and im cool
