The gate voltage controls the extent of depletion layer and
thereby controls the width of the channel. As the width of the
channel varies, current also varies. Width of the channel is
inversly proportional to drain current.

depends on the width and each width can have up to 3 distinct
weights?

if channel width decreases , the drain current(Id) will also
decrease .
but , Id will decrease up to a certain limit , when the jfet is
in pinch off condition i.e. channel width is tends to zero (Vgs is
very high) the Id will be constant then.

Simply because of the band-width required to transmit and
receive calls. If the channel spacing was narrower - they'd need to
reduce the band-width - which would reduce the amount of data they
could transmit.
