No, you need a path to ground for any current to flow. You need a difference in electrical potential more specifically.

When insulated, there is no difference. Your potential is “floating”.

Well, more correctly the difference needs to exceed the breakdown voltage of the insulation barrier. Or (depending on the insulator) some current might flow the entire time, but a limited amount.
