It hasn't been bad so far, similar regulations have been around since 1938 and updated in 74; Sweden punches way above its size in economic output, the country's labour market was built on this foundation and it's worked pretty damn well.
I think Sweden will be absolutely fine if Tesla packs up and leaves, it's not like the market disappears because they left, there's just more space for competitors to take over Tesla's marketshare.
That's the point?
