I agree that trust is a big part of loyalty. Consider this: it is much easier to trust something/ someone if you do not have many options to choose from. This is where freedom plays a role, because with freedom we now have an abundance of options and choices, so our loyalty is tested more so than perhaps ever before. When there is no freedom, then there are no choices then it's much easier to be loyal. Let's look at a country like Venezuela. citizens of that country have little freedom, few choices, so of course they will be loyal to certain products/people. But you are correct, there are instances when people, even when presented with many different choices, will stick to that one tried-and-true product. But even they, I think, will start to contemplate other options if that product begins to falter or stop serving that person's interests.
