Cloud flying is forbidden in the USA

This is not correct. Cloud flying is permitted in the USA, in
controlled airspace on an IFR flight plan or in uncontrolled airspace
with no flight plan. There's not much uncontrolled airspace suitable
for cloud flying, though. There are pilot certification and recency
of experience requirements in Part 61.

More explicitly, an Instrument Rating is required for the pilot.
