why was the san francisco tower of jewels demolished?

the 1915 San Francisco World's Fair/Expo for the Panama Canal was an excercise in demolishing the enormous complex architecture built by a previous civilization. The Tower of Jewels was a massive structure in the Marina, just one of many marvels, had over 125,000 jeweled mirrors adorning it, and was brilliant when lit up. These structures were inconvenient to the narratives of westward expansion and had to be supposed to be created as temporary, displayed publically in a "fair" and then demolished (not without considerable effort I'd imagine). Although photography was wide spread at the time, most depictions of this event downplay it's beauty and brilliance, the official periodicals and books of the fair offer distractions of technology and culture to amplify the prominence of the emerging fossil fuel and electricity techology, and minimize the undeniable master masonry and buildings that were already present in the bay area stretching back decades, and perhaps centuries. The Palace of Fine arts still stands, although the history and multiple claims of "retrofit", fire, and "remodelling" continue to stand in internet historical on bizarre grounds as far as explaining who what and why they were built. The timelines of such structures, coupled with the stated population of skilled builders of westward pioneers and difficulty in their construction, such as building in what is essentially a seaside wetlands/swamp, only over shadowed by the question of:

"Why would anyone in their right mind tear them down?"

The photos match the stylie of other still standing structures nearby like the Ferry Building, but the Tower of Jewels is a fascinating relic and piece of evidence that the history of San Francisco is largely a giant fabrication. As to what the purpose of that might be, that is an exercise left to the reader, but it is obvious to any common sense person that such buildings would never be built in such a incredible detailed massive way unless it was a purposeful, expensive and form-factor driven endeavor, requiring masters of their architectural craft to complete.

Even to do this with plaster would take years, let along in a wetland, with bay area weather elements, millions of dollars, and skilled laborers... there is not adequate documentation to support the official story of this wonderful structure.
