Why don't they design the towers so they can be laid down flat and fixed on the ground and then pushed back upright again?

[kaikai]

I can’t tell if this is a serious question. Towers this size are built in place, being able to handle the strain of being lifted from horizontal would be wild. Much easier and cheaper to pay a climber.

Ok. Lowering a huge tower to the ground pretty silly. How about designing the array at the top as a platform that could be lowered. Too much extra weight/cost?

[quesera]

Some very large towers do indeed have platforms at the top. And some even have elevators.

But the vast majority do not. Very expensive to build.

If I think about all the things that ca go wrong with folding huge tower, sending people to climb one seems like a fair trade.

I'd assume physics are the biggest constraint here. Just look at the machinery and equipment needed to raise a falcon 9 which is "only" ~230 ft tall.

[SpaghettiCthulu]

Because then you need a 1115 ft stretch of flat ground to lay it on?

Then make it collapse in a spiral. Then, assuming you can make it infinitely thin, you can collapse into an arbitrarily small area.
