I don’t think it would be that difficult for him to “destroy” it in the sense of making it no longer a practical method of imprisonment. All he would have to do is start disseminating knowledge of the true patronus charm, and using dementors as the primary guards of a prison would cease to be viable.
People could still be tormented by the dementors when their wands are taken away, and left unable to escape, but using dementors as a torture device which itself needs to be guarded from anyone who might decide to obliterate them all is probably a lot less politically viable.
In terms of retaining political advantage, this may not be the best method available to him, but it may be the easiest.
Attempting to coerce the dementors directly and break their pact with the Ministry retains more power, as does taking away everyone else’s ability to use patronuses, leaving himself in control of the dementors, but both are vulnerable to interventions such as, say, kidnapping him and crucioing him until he surrenders.
There is no reason to think he doesn’t need his wand for actual Dementor crushing. The Dementor scaring wasn’t him casting anything. It was due to Dementor’s own ability to commune with Harry turned against it (plus, hypothetically, some expectation manipulation—the “BOO” there was probably more than just for show, but also to prime Harry’s mind into expecting the thing to be spooked).
Normal wizards need their wands and the ability to cast patronus in order to deal with a dementor on their own.
Harry can deal with dementors without his wand. That is, they cannot eat away at him. He can stand in their presence without becoming demented. And that is unusual.

Harry doesn’t need his wand. I think that’s only because he mastered his Hallow.
