Your 3rd point doesn't really stand up as nature has been genetically engineering plants for far longer than humans. The sweet potato for example has had DNA implanted from other species via the agrobacterium. There are other examples out there. Also nearly every vegetable has been modified via breeding as the wild counterpart is a lot less edible. For example bananas and watermelons used to have a lot more seeds.
