That's why this is a matter of trust. Either you trust the government and allow it to collect the data, or you don't trust the government and don't allow anyone to collect it. The government has the monopoly on violence. It always has access to the data held by private parties. The government and the people serving it may choose to respect laws and other promises. They may choose to avoid accessing private data without a valid reason. But if the government chooses otherwise and requires private businesses to hand over their data, the businesses will most likely comply. If you don't want to give a government-turned-bad access to some data, that data must not be allowed to exist in the first place.
