>So high taxes might still be an issue, if the 'sweet spot' isn't too low.


Easy enough to test for.
The sweet spot is 160% for not losing population.

Keep in mind:
This requires Growth+3, which you are negating with this strategy.
The bonus income looks to be about 110 gold per turn (with maxish exconmics).
However you must keep 40ish troops on patrol to supress the unrest, which cost approximately 400 gold and have an upkeep of about 60.
Thus the income bonus is about 50 gold.
Next account for the fact that sometimes the patrols miss and you take a hit from unrest, which intrudes heavily on tax income.

So for 120 nation points you'd squeeze out a few extra coins here and there. Not worthwhile compared to just allowing the growth scale to pump the popuation normally.

It's entirely possible that my scales may have issues, but I don't think growth/patrolling is one of them.
