Since they live around Seattle, maybe they should consider immigrating a few hundred miles north to Canada? They might qualify under the self-employed artist category?

The hope is that they earn enough from the Steam royalties (which should happen given the popular rumor and storytelling around the game among gamers).
Also, Canada has medical requirements and refuses immigrants whose admission "might cause excessive demand on existing social or health services provided by the government":

There are private clinics here if you have money and don't want to wait, but of course it doesn't cover very specialized things. When I wanted to see a dermatologist, I would have had to wait 1-2 months for my first appointment in the public sector. I went to a private clinic and paid 200$ (plus like 75$ each subsequent visits) and was seen in 2 days.
If you have a life-threatening condition, you're not gonna wait months. If they can't do the operation in Canada because of whatever is lacking (including equipment or personnel), they can send you to the US and the government will pay for it.

Also, wealthy persons will travel to a foreign country if that country is like to have a "world-leading" specialist in a certain surgery. Sometimes this place is the US, sometimes it's Canada, sometimes it's the EU.
Furthermore, if you want private care in Canada, you can receive it. I'm not sure any of your points make sense in light of the above.

The clause about barring excessive health costs isn't unreasonable, Canada, as a country, is basically an insurer and is being dickish about letting people with pre-existing conditions onto their insurance who haven't paid into it, this is a defense against the US's broken system that would encourage all sick citizens to flee to Canada. That said when I immigrated I had several long term health issues that posed no barrier to entry and the cases where this is enforced are rather rare.
Canadian healthcare is perfectly fine, but it isn't your rebound date when the US healthcare fails you. People shouldn't immigrate just to take advantage of the system.
All that said, I am hopeful you guys will get Medicare for all down there and actually cut your costs-per-patient and enable people to be more free to pursue their individual liberties.
It's unlikely you'll find higher quality or more timely care in the US than Canada for anything that would be triaged as urgent (such as a cancer scare). The entire ethos of the Canadian healthcare system is that there should be a single tier system regardless if you're wealthy or poor--everyone gets the same quality of care. This means triaging happens based on urgency of treatment instead who has the most money.
You will certainly be able to bypass any triaging in the US for elective or non-urgent matters, for a sufficient premium (effectively a bribe).
If you're comparing quality with Seattle specifically, then compare against Toronto which has some of the best cancer treatment facilities and doctors.
