Why can't grounding steel be used?

Why can't grounding steel be used?

Answer:

In addition, the skin effect of the current, the thread of the threaded steel surface, is equivalent to the addition of an inductance, which is detrimental to the rapid unloading of the high-frequency lightning current
When the thread steel is grounded, the contact with the soil is not dense, and the grounding resistance value is increased
The edge of the thread of the thread will have a point charge accumulation discharge, and the uniform dispersion of the ground current is unfavorable
