For one, I had a GoPro whose sensor broke after about 20 minutes of recorded. I ended up getting 3 different replacements, all of which also broke. In the end I just forgot about it when my home burnt down in a wildfire. I got an Insta360 with better picture quality that's also been more reliable for a similar cost.
And I would have loved to buy a Prusa printer but I got a Bambu P1S combo for $600, an equivalent Prusa plus the $300 shipping to Canada would have been ~$2500 CAD. For making trinkets for my 3 year old son plus the few random other things I'd make it's not worth it to pay 4x the money.
Maybe it'll forever be this way due to the differences in cost of living but I do feel as though there's a million barriers to entry to building a business in North America, at least a business that's not fully online.
