It'd be a huge gamble. Many things can't be replaced. Mostly you'll be forced to get "similar" things. Different manufactures. Different model numbers. Enshittification means that you'll often be stuck with something much worse than what you had.

With prices about to skyrocket and shelves about to be empty thanks to tariffs, mismanagement of the economy, and pissing off the people we depend on for nearly everything we have you'd have to be crazy to throw out everything you have and assume you'll save money buying new replacements for everything you lost.
