It is easy science and engineering to make the tower base infinitely large,

large, greasy, conductive, and stout you can get for a buck and stay within
the desired safety and performance parameters.
Exactly right. I recall a great story from my days in EE school. A
mathematician and an engineer were out drinking, and noted a lovely
young thing at the other end of the bar. They wagered that they could
move half the distance between themselves and the sweet young thing with
each drink. The mathematician never got there, but the engineer got
close enough for practical purposes.
Engineering is the practical application of science. I just returned
from two days at a meeting of the Acoustical Society of America, where I
heard many presentations about exactly that -- the practical application
of science to solve problems in acoustics. I told one myself, about an
acoustician who had died a year ago and was being honored, and it was
one he had told to a group in a workshop I attended 30 years previous.
His client was the owner of a home recording studio, and the problem was
that he was hearing excessive traffic noise. The "knee jerk" solution
was quite expensive -- a room within a room with floating floors, air
space between rooms, isolating doors, and so on. The acoustician
surveyed the situation, did some mental sums of costs of various
solutions, and told his client to hire a paving contractor to fill the
potholes in the road.
