But you didn't answer my question.

How would *I* do it when I'm not remotely located near uncontrolled
airspace?


That's not what you asked. You asked how remaining clear of Class B, C, and
D airspace presented no problem. Where there is little such airspace it's
easy, where such airspace is prevalent it's rather hard. You did not
specify a location.
