Considering VAT being used by the government to pay interest-based loans, is buying things in shops haram?

Each country (except a few, probably) takes loans from central banks, and then uses this money for various purposes. To pay back that money, they take taxes and VAT that people pay, and pay their interest based loan. So every time I buy a Samsung phone on the Samsung website, Samsung the company will pay some VAT to the government (this is also true for KFC, shopping centers, etc.), who in turn will use it to pay their interest based loan Can I safely buy some chocolate, or unnecessary groceries at shops?
