Sure, Django here is the exception, but not taxing imports would generally not benefit people like him, but the actually wealthy people who can otherwise afford the tax.
"Effectively charge a 33% tax on all foreign goods and services." Not just Macbooks. I don't know if this is the final definitive tally of the tariffs but I believe almost everything has a high tariff, so people effectively pay 33% more for the same goods plus shipping. Fair, can't really get rid of shipping, but a 33% or even a 15% penalty on tools means people get worse tools. Computers, mobile phones, cars, motorcycle helmets, medicines (if imported perhaps?), hammers, fans, showers, whatever tool you might use that is a finished good coming from another country, you pay 15-33% or whatever more, so you get a lower quality product for the money you have. I just would prefer my people get the best deal on the best tools (that we as a country don't think we need to make for security reasons) so people can improve faster. Less smog, better roads, fewer things that break...would be quite nice at all levels.
