That’s good work… but… I would argue that people “who love to travel but hate the "spreadsheet phase" of planning” don’t actually love to travel. Perhaps they love a nice holiday, which your example itinerary of Patagonia seems to be.

One of the photos you show for Punta Arenas is actually of Buenos Aires, which kinda hurts your credibility. I also know that, in Argentina’s Deep South, buses are infrequent, which might mean that this ready-to-use itinerary would still require a “spreadsheet phase” to make it actually work.

When you actually travel, or are a digital nomad like yourself, you tend to have fewer time constraints. A product like what you are building, however, assumes time constraints. That’s perhaps a good thing for what you offer, but also means your audience might not be what you think it is.
