Confirmation of the topology of the Wendelstein 7-X stellarator’s magnetic field

How small can these stellarators get? Is there a necessary minimum strength magnetic field that basically creates a minimum size for a stellarator?

I'd say the smaller the Stellerator is, the stronger the magnetic fields have to be, as the curve radiuses are smaller

So there's probably an ideal size

my math suggests something approximating the size of a star could achieve fusion by using only gravity for containment.

I wouldn't want to stand too close to that sucker though.

If someone had built such an object, say 10,000 light years away, what would it look like to us?

nothing for 10,000 years - however long ago they built it.

I read this as such dry humor, I have to ask if you are English.

but aren't stars varying extremely in size?

Woosh.

A star is a fusion reactor using only gravity for containment.

Well, they're only just barely contained. Things spew out radiation like nobody's business.
