You use appropriate bottom bracket widths to fit a crankset so that a chainline is parallel to the center-plane of the bicycle. The only reason people "don't get it" is because what you are saying is inherent nonsense.
Go buy one and flip it over, you will find inner chainring tabs. Of course, there's not really any such thing as a "road" or "track" crank, but Sugino was selling the RD as a
Road
Double for years before this whole SS/FG thing got going.
The sugino RD has a chainline of 45mm in the outer position when used with the recommended sugino 103mm JIS BB. This "inherent nonsense" can be found on the Sugino web page:

This crank will have bad chainline unless you use it with the ring in the inner position with a longer BB.
