Do you think that it is possible to have true communism?

Is complete communism possible? What is your reasoning?

I feel that communism is an impossible goal for several reasons, the first of which being that people will always want things- they don’t just want their needs to be met, they want their needs to be met and then some. Second of all, the majority of people in the world are religious, while communism seeks to abolish religion. Thirdly, people generally object change, especially change that would take things away from them- a communist revolution would not succeed over the people easily. Furthermore, communism would require redistribution of everything, which would take money, lots of time, a large government, and complete cooperation from the constituents. In addition, communism directly contradicts the constitution of the United States, as well as the constitutions of most other countries, and therefore would not be an easy or gradual transition.
