"Does any of this actually matter?" Yes. If we want others to respect open source licenses, we need to honor them ourselves. We can't assume that source-available is "available for all uses".

Doesn't this presume that all property is taxed at a flat rate? Wouldn't the answer be to split the property based on what the city wants to accomplish? Then empty land can be taxed at a different rate to property with a residence

Property Taxes aren't terrible for old people. How the mille-rate is set is terrible for old people. A fixed mille-rate results in taxes going up as value goes up. This might be difficult to plan for and manage. However, many cities wi

Data from Drake's Landing in Aberta has a COP of 30 (30kw of heat per kw of electricity)? The heat stored is waste heat - otherwise lost to the atmosphere, so storing it until use is should be compared to typical heat pump COP of 2-4.

If a programmer is paid per hour, then this is only worthwhile if it increases their hourly wage. Otherwise, it's just another cost. Now, if they are paid per job and it makes them more productive... That's different.
