Neither is capitalism as implemented today, as people with power either control capital and thus workers indirectly and are entirely above any important personal repercussions.

The main difference is that communism is bottom up pyramid of societies, while capitalism is a top down pyramid of companies.

If you think capitalism is not coercive, why do you go to work every day for less value than you produce? Contracts are based on enforcement too. The root word in there is force.
