Might be happiness for some, but it's certainly not freedom, in any normal sense of the word.
In what sense? Aside from whether it's practical to really desire nothing, if you could wouldn't you be free by definition because you could do and have absolutely everything you wanted, that being nothing?
At the very least and no matter how humble your threshold is, everyone wants food, shelter and some kind of company.
The first 2 cannot be attained for free in our world's ergo, you cannot be free from whatever obligations you may incurr to procure them

I think there's an important distinction to make with this: contentment vs complacency. They're similar, but distinct. Contentment resonates more with the gratefulness aspect of your statement, whereas "wanting nothing" leans more toward complacency.

In addition, I would argue that it's impossible for a human to truly "want nothing" (sorry Buddhist friends). Even the most enlightened soul would desire to see peace throughout the world. In fact, if you truly wanted nothing, I don't think gratefulness would even be possible--what is there to be grateful for if you didn't want any of it in the first place?

Sounds like propaganda from horrible dystopian society.
