Process of elimination:

By and large, the first option is not true: 70% of food in American grocery stores has been genetically engineered so plainly a mass market does exist for these goods. Increasing the quality of one crop has no effect on others. And the costs of engineering crops are offset (at a profit) by higher production and lower pesticide needs of GE crops...

And resulting crops do have to be monitored and re-engineered. The moment a pathogen evolves which is able to colonize a certain plant, all the members of the plant species will be susceptible and so will need to be modified again.
