You really can't.

If you don't want to be homeless, you're either renting or buying, and in either case people are going to be processing your personal data. You're also probably going to need a bank account, which you also can't open without handing over personal data.

If you want electricity, you're then dealing with another company that is processing your data. Same for water and gas and internet.

Sure, some things are optional, some things can be worked around by buying in person and using cash instead of buying online. But a lot of things are just not practically optional.
