Most type of volunteer works require more people, with some level of organizations before it becomes effective.
While open-source software projects are often started by one very good SWE, as a hobby, in his own time: a very low barrier of entry. Plus, a project can live with a solo maintainer for a very long time. Though, I digress that can be detrimental in the long run, like the recent xz-utils fiasco.
A huge chunk of cost increases in modern high rise building (outside of land and taxes) is due to ever more stringent fire safety requirements.
I don’t, I’m grateful for those people existing. Regarding safety regulations, those were most often driven by tragedies that occurred prior to those regulations being in place. I prefer being alive over saving money
But trust me, I understand the sentiment. Housing becoming increasingly unattainable is a issue on many levels, I just think that there are other, worse, contributing factors to the overall situation. Compromising on fire safety or other reasonable safety factors effectively won't help anybody when there still is an ever increasing amount of institutional investment hiking prices on the market.
