This is completely wrong and I'll even show you how it's wrong.
Take health care, for example.
Right now, you are free to see a doctor...so long as you have health insurance, and so long as that doctor accepts your health insurance.
But that's the extent of your freedom.
You are not free to choose any doctor you want in our current system because of provider networks.
So you are limited in your freedoms to choose the provider for your health care from a list of doctors pre-approved by your insurance company.
If you want to go to a doctor that isn't on that list, you have to pay extra in addition to paying the premiums and deductibles you already pay your insurance company for access to the pre-approved doctors they chose for you.
In a single payer health care system, there are no provider groups, so there are no out of network doctors, which means you can go to any doctor you want.
Is that more or less freedom than being able to only go to the doctors your insurance company says are OK?
