A major consequence of invisible trade is that eventually the amount of invisibilities will exceed the payments for them. This means that the goods and services provided will be given, but payment for them is often neglected. This leads to a devastating deficit in funds. So the person or business supplying the goods can be in ruin, along with the person or business owing the money. This could threaten the economic strength of Texas.
With war, every country is afraid. They're afraid of possibly being ambushed, becoming in dept, and many other reasons. So by remaining neutral they can sit back and not have to worry about being attacked by any country that's fighting. But that's not always the case now and days. Hope I answered your question correctly.

This would be referring to the Homestead Act! They would give the land to anyone who was willing to work on or improve the land.
The land was given almost free of cost and all the new owner of the land was required to do, was work the land until it was ready for farming/crops, and then they had to build a house for themselves (and possibly their family).
