Don’t use any computers? That is impossible even if a non American company all parts are american.

Most of the silicon in a typical PC or phone is not fabbed in the USA. Leading-edge CPUs, GPUs, and SoCs are overwhelmingly manufactured by TSMC in Taiwan (AMD, Apple Silicon, NVIDIA, and increasingly Intel's own tiles). Leading-edge DRAM comes from South Korea and Taiwan. NAND flash comes from South Korea, Japan, and Singapore. The actual PCB boards, capacitors, and assembly are mostly China and Taiwan. Intel does have some US fab capacity, but even their recent desktop chips (Arrow Lake) used TSMC silicon. There simply isn't much of a modern consumer computing device that was physically manufactured inside the USA.
Credit cards american companies.
Haven't had a credit card since 2001. I don't live in a technological backwater like the USA.
It's very easy to live USA-free. You just have to stop drinking the American Kool-Aid and realize that the USA is the consumer of tech innovation, not the maker.
