By that logic, do you open the curtains during the day to let in cheap
imported light, or keep them closed and support the local utility?

To carry the parallel even further, does it matter if you use that
imported light directly from the source, or merely after it has been
processed biologically, decomposed and compressed for a Very Long
Time, dug/pumped back up, and then converted to a portable form to be
sold to you at considerable markup? In the end, it all comes from the
same "remotely located unshielded fusion reactor"* after all...
