I think I must have been asleep when I wrote that. I think my point was more related to the lower energy levels than good advice. A single layer of tap is good for about 300 volts but tape has little or no mechanical strength against tearing or compressing to failure so no tape is not adequate.
A real use of insulated tools would be when performing live testing and troubleshooting which are about the only place for live work. Unless the power is life support i think most places can turn the power off.
So the need for insulated tools is less than in the past but until the power is proven off I think another level of safety is a good thing.
