If you don't have any problem with your daily itenary beinf tracked, then no explanation will be good enough for you.
Just respect the fact that people don't want their daily activities available to 3rd parties
It is not only you. The more people are OK with this, the higher the danger for other people, who are not OK with this, because data adds up and usually becomes more information than the sum of its parts. Tracking and spying are a danger to people, whose work requires them to not be tracked and found. People like journalists in oppressive regimes. While people run around merily sacrificing their privacy for the reason, that they are uninformed about these issues, they indirectly play into the hands of those, who want to make journalists shut up and disappear.
Privacy is vital for a functioning society. If not for you personally, then for others. By adding yourself to the mass of people, who do not care, you are helping in creating an environment, where privacy is not valued. Seen as something "only a few radicals want". Quickly abolished by governments in the name of "but think of the children!" or "but think of the terrorists!" and similar nonsense.
