Of course, there will be political competition on local regions. Even HA and Amal may clash in Shiites dominated districts.
A ka2em makam in Bshareh may likely be an lfer while FPM in Kesserwen.
This is another way to create small central government. It effects on Lebanese daily life will be minimal.
It's main task is foreign affairs, defense. The Parliament shall take out sectarian quota as long as any constitutional reform needs a unanimous vote.
The fact is that even with a smaller central government, you're going to have regional and international interference through the Lebanese sectarian puppets. The same issues you have now will come up again come decision making time.
As for the regional governments, if the current political class stays in power, they will simply eat the taxes and wealth of the regions. Like they ate and are still eating Lebanon's wealth today.
