Answer:
Freedom is costly, but anything truly worthwhile comes at a high price.
Step-by-step explanation:
This is the feeling that Paine wants to convey in these lines. He tells us that when people obtain things cheaply (with no effort), they steem them lightly, which means that they do not appreciate them enough. Therefore, he argues that things that are truly valuable are usually difficult to obtain. This is the case with freedom. Freedom is going to be difficult to get, as it will require a war. However, this is only because of the importance and value of freedom.
