No. You were repeating fossil fuel propaganda unrelated to the issue at hand.

You only dog whistled it but it's obvious nonetheless.
You're talking about more land, more pollution and more long term costin the form of gas.

The worst areas are within easy transmission range of somewhere with a winter capacity factor over 8%.
Power density is around 1MW/ha nameplate when land optimized. This is under 70m^2 (8m x 8m) per person to provide world final energy of around 10TW. This land can coexist with many other uses (such as roofs, car parking, and agrivoltaics)
The fact that you're pearl clutching over this, but not over the average 8 car parks per person at 40m^2 each or the land required to support eating beef makes your motivations fairly clear.

Solar uses less land than coal extraction or the largest uranium mines per unit power. There is no choice with lower impact.

Even outside of western China there are India, myanmar, vietnam, cambodia, nepal and mongolia which all have substantial renewable resources. It's not clear that the cost of export is lower than the cost of local production and overland transmission.
Indonesia and PNG are good candidates though.

Behind the meter solar + battery will cost less than transmission upgrades to meet electrification needs very soon. It will be the plurality if not the majority of energy in the areas where 90% of the people live. Not only covering the overwhelming majority of home and low rise commercial energy and heating, small scale agriculture, private transport and light commercial transport but also exporting enough during summer to feed a big part of non-time-critical industrial usage like electrolysers for chemical feedstock. This will be over half of world energy.
Energy that doesn't pass through a single floor or low rise building at some point (ie. Heavy transport, high rise commercial, heavy industrial) will probably not have micro generation as a major component but more as an opportunistic suppliment.

Except it's not a real concern when its less bad than any other option. By all means push for less land use, but pick the low hanging fruit first.
