I'm often extremely price-constrained, so I'm open to at least a few software options that I can buy later, like supercharging. But I seriously doubt at a $2,000 price point that I wouldn't eventually get it. There are many months of the year that I tend to travel far and wide.
Speaking of software options, I'd be very disagreeable if Model 3 were artificially crappy in ways that would cost Tesla almost nothing to make nice, just so they can move more people into the Model S zone. For instance, almost all the software options would be pretty cheap to manufacture, such as driving assistance packages, valet parking mode, anti-theft programming, detailed multistop traffic aware trip planning, etc.. As I've said in another post, all the great stuff that is cheap to do and the good stuff that is almost free to do should be done, and all the stuff that is expensive to do should be on the question list. None of this has to do with supercharging; I consider supercharging to be an energy purchase issue.

This is exactly the group that would also be willing to buy Nissan Leaf 2 or other EVs instead of Model 3.
The other group would be people for whom SC is still too inconvenient - after all SC needs to be much more dense and well spread to compete with the convenience of gas. These people would also assign lower importance to SC and would be willing to get other EVs.
If the Leaf 2 passes all the safety tests with superb scores including the "small overlap front crash IIHS", and is safer than the Leaf 1 in every regard by leaps and bounds, then I will consider the Leaf just as much as I consider a Model 3, head to head. As it is, I would already have a Leaf now if it weren't for the failure in the small overlap front crash test. That is by far and away the hugest deal for me: safety. That's one of the reasons I went with a used Mercedes for my current vehicle (locally there's lots of those available used, a status that used to be true for Volvo but no longer is). The only cars I've ever bought were Volvos (3) and Mercedes (2), so far.
I find it bizarre the BMW 3 series is what Tesla is competing with, personally, since I hate BMW in every way. Go figure. (I used to commute in the back seat of one during high school for an hour every week, and it was miserable.)
