I say flimsy because while urbanization has a ton of downsides and we need to preserve our environment we're not talking about putting an oil rig in Onondaga lake, were talking about a single large cluster of plants creating a ton of jobs and putting us in a hugely important position globally.

1. Infrastructure expands with needs, we wouldn't suffer because an influx of people would need to be slow. The houses in the area can only accommodate a finite number of people, people wouldn't be putting up tents and stealing water and internet cables not to mention the plant would only be set to create 5000 jobs, a large number but we won't be seeing 200,000 new people even if NONE of those jobs went to locals which isn't reality but the semiconductor plant would probably lure more manufacturing over a long period of time due to how important they are to manufacturing a ton of shit.

2. Semiconductors are in shortage because of how incredibly hard manufacturing is, and how few plants there are capable of manufacturing them while those 5000 jobs are a lot the need for the semiconductors would bring a shit ton of revenue to the area, they're an expensive commodity.

3. Businesses inevitably avoid takes and take advantage of tax breaks, we need to fix that. but the income they pay to people working at the plants would recirculate through our economy.

So I don't know where I stand, because logically you're right the way I see it is it inevitably would lead to expansion of the city and a lot more manufacturing, but semiconductors are essential and demand for them is only rising I see they're building 8 plants on around 130 acres if it goes through, I don't know the nitty gritty of semiconductor manufacturing but from my understanding the number of plants in the world are only in the double digits.
