Forgive my bluntness, but plants are like animals to me.
If you do not take care of a plant, you do not need it.
I had a fig tree die to the ground in zone 7b/8a.
After this happening more then once, I found out that old wood stands up better to cold.
I also found out that you should water fig trees once a week in the winter in South Carolina.
So I have learned a lot from this forum.

Never heard of doing this. Family tree was over 20 years old, big as a shed, unwatered, unpruned and unfertilized. Nearly a hundred figs each year. Amazing.

But were it cut to the ground, how big could it grow each year? How many figs could one expect from such a tree? Makes no sense to me. Just sayin'.

Some trees don't produce a breba crop or the breba crop does not ripen because it needs to be pollinated or just does not taste good. In such cases I have heard of people severely pruning their trees back while dormant. The next season they grow lots of new wood which produce main crop figs. However I have never heard of anyone who cuts them all the way to the ground.

Remember; The breba crop is grown on last seasons wood. The main crop is grown on new wood thats grown the current year.
