Hello, could you please elaborate about those laws?

The Jones Act requires that all goods transported by water between US ports be carried on ships that were built in the US, fly the US flag, and crewed by US citizens. That effectively makes it impossible to ship oil between US states at scale without a direct pipeline.

Though to be clear I believe we would still be a net exporter without the Jones Act, it's just one of those weird things about the US oil industry.
