Jesus said not to break the law. The bookstore isn’t doing that.
Then the Pharisees went and plotted how to entangle him in his words. And they sent their disciples to him, along with the Herodians, saying, “Teacher, we know that you are true and teach the way of God truthfully, and you do not care about anyone’s opinion, for you are not swayed by appearances. Tell us, then, what you think. Is it lawful to pay taxes to Caesar, or not?” But Jesus, aware of their malice, said, “Why put me to the test, you hypocrites? Show me the coin for the tax.” And they brought him a denarius. And Jesus said to them, “Whose likeness and inscription is this?” They said, “Caesar’s.” Then he said to them, “Therefore render to Caesar the things that are Caesar’s, and to God the things that are God’s.” When they heard it, they marvelled. And they left him and went away. -Mt 22:15-22
That said, later, Jesus also said God’s laws can take precedence over any human laws. The point of paying taxes isn’t to be doormats. Discernment is permitted. This is why some Mennonites in different places refused to pay taxes because of wars started by various governments.
But when the Pharisees heard that he had silenced the Sadducees, they gathered together. And one of them, a lawyer, asked him a question to test him. “Teacher, which is the great commandment in the Law?” And he said to him, “You shall love the Lord your God with all your heart and with all your soul and with all your mind. This is the great and first commandment. -Mt 22:34-37
