Nobody is saying that without a time limit and at great expence sand can not be manufactured, but it is not even that simple.
Firstly : You would have to quarry your rock of preference before crushing, sieving, grading, and more than likely, also having to transport your specific rock grains to be mixed with other types of crushed and graded chips, depending on your sands ultimate purpose.
Secondly : It is not cheap to extract stone from the earth plus quarrying leaves very big holes in the ground! Permission from authorities to open new quarries or pits is not easily obtained in most countries.
Thirdly: Crushing is hazardous, polluting, environmentally destructive and very expensive .
The sand problem has been bubbling away on the back burner for years, hence the many and various ongoing efforts from all around the globe to recycle or create new and innovative construction materials.
I don't get what you're trying to say. My assertion was that this is nothing more than an economics issue - as easily obtainable sand is depleted, manmade sources will come online to fill the gap, and the only thing preventing this at the moment is pricing. You've listed a bunch of logistic issues, which again is nothing that money will not solve.
And again, what you consider to be merely an economic issue is exactly where you seem to be missing the point.
Quarrying is environmentally destructive. It has contamination and pollution issues. It carries health issues. As well as the costly logistics of transporting bulk around the planet. Governments these days no longer wish any company, large or small, to go around tearing rock, in any form - pre ground or otherwise -out of the ground. So your next problem would be sourcing the base materials for your manufactured product legally.
Economically, even if you did manage to quarry,crush,sieve,grade and mix your sand for lets say £1000 a ton. What architect on the planet would specify the use of such an environmentally unfriendly and costly material and what construction company in the world would pay such a price?
Architects are already specifying more sustainable materials and construction techniques are changeing, but at present, people are still destroying the planet and killing each other for sand ! That's the current economic situation.
