".....
is there any reason for why I should anyway?"
There absolutely is a reason you should file a 1041; you can pass that capital loss through to the beneficiary(ies).
Further, you will need to file a 1041 if you receive a tax reporting form, such as a 1099-S. Despite the fact that the filing threshold is not met, the IRS will not know the basis of the property unless you report it on a 1041.
