It makes it more economical to boycott,
I guess technically? It makes boycotting more economically "sensible" but just because it makes it less economical to not boycott. It doesn't really benefit the people boycotting, it just penalizes those that for some reason don't.
If I could just pick and choose, I be down for keeping some targeted retaliatory tariffs up because I see the value in forcing the hand of people that would be otherwise indifferent (or worse) but most of the damage we've been doing to the US is not really tariff driven, e.g. booze, travel, groceries.
