That works to a point. First consumption taxes are regressive and affect poor(er) people more than wealthier ones as the former pay a higher percentage of their income on just living. Second, not everything can be purchased second-hand, like food, and not all food is grown domestically. For example, very few bananas and very little coffee is grown in the U.S.. Also some things are made with imported parts/materials no matter who makes them, which limits consumer choice to buy domestic.
A related point is that Trump isn't using his tariffs for the reasons tariffs exist. For example, he's put a 50% tariff on Brazil because he doesn't like that they are prosecuting their former president for attempting a coup after losing the last election (wonder why /s); and he's increased the tariff on Canada to 35% because they're considering recognizing a Palestinian State. Further, those reasons don't fall under even the flimsiest interpretation of the emergency powers law Trump is using to implement his tariffs - the trade court has already ruled his other interpretations are bogus, stayed pending appeal) and Thursday all 11 members on the appeals court seemed very skeptical of his administration's arguments.
