1) If providing the service is a requirement for licensing, it is not “pro bono” but rather is just a tax (paid by labor).
2) As with mandatory continuing legal education, the administration of mandatory pro bono would provide jobs to many unemployed lawyers (of which there are very many).

A haiku:
We’d be better off
If the uppity beaner
Just cleaned my toilet
and:
We’d be better served
If her wisdom directed
To scrubbing commode
and:
The wise latina
After the revolution
Has date with rope
as an aside:
Wait a minute
You forgot tortillas?
Then GTFO
