What science calls organic as far as chemicals are concerned is anything that contains carbon and hydrogen. What government calls organic is anything that came from a living source.
I think government organic is an artificial distinction that makes little to no sense.
The purpose of the Organic Movement was to develop a set of practices and guidelines that would not destroy the soil and garden ecosystem, but rebuild it.
One key strategy involves a focus on increasing
organic matter in the soil. This is where the name of the movement comes from.
Soil organic matter is mostly semi-degraded cellulose and lignin - a.k.a. humus. It acts as a sponge for water and nutrients and is associated with higher soil fertility. It is generally an indicator for soil microbes, earthworms, and a complex soil ecosystem. Quite apart from other uses of the word 'organic,' soil organic matter is a precise and logical term that has real meaning.
Another key strategy for the organic movement involves limiting the type of pesticides used, and the frequency of pesticide applications.
These general principles are quite sound, and (whether appreciated or not) are a general component of permaculture.
The big problem with organic standards in my opinion is that is sometimes possible to follow them to the letter, and yet to violate the basic goal of regenerating the garden ecosystem. This is not surprising because ecosystems are quite complex, while organic practitioners must typically balance short term production against long term sustainability, and human understanding of the complex systems is limited.
Nitrogen fertilizers in particular are damaging to soil organic matter, as nitrogen is a limiting nutrient to the microbes that oxidize organic matter. Add too much nitrogen, and the soil is degraded. This is why the organic movement prohibits many concentrated sources of nitrogen - there was a reaction against the damage to soils seen after Fritz Haber developed a process for industrial fixation of nitrogen and farmers started pumping the soils with synthesized ammonia or nitrate or urea.
But even when the nitrogen is from a source approved by current organic guidelines, it can destroy soil organic matter if levels are too high. And going to the opposite direction, if nitrogen is too low, plants grow slower and yield less. There is a rather narrow zone of nitrogen levels where the soil is not catabolized, but where plant yields are also high.
Tilling the soil is another area where organic standards are rather lacking - organic gardeners and farmers assume that tilling is normal, natural, and acceptable. Yet it is typically quite damaging to the soil ecosystem and works against the basic aims of the organic movement.
The government definition of organic in relation to agriculture came from an attempt to standardize the term and enforce the standards. If anyone is allowed to call anything 'organic', then the word has no meaning. While there is occasionally tension over the standards based on different ideas of what the organic movement is about, I think the USDA has generally done a fair job of codifying organic practices. In the long run, if organic thinking changes, the standards can be updated to reflect the new thinking.
And of course, any human code has the potential for fraud. People want wholesome, unadulterated food or medicine, but there will always be someone who tries to sell something even when they know it is contaminated... regulators cannot be everywhere and test everything. People want to buy real artwork or antiques, but there will always be people trying to pull a fast one and sell forgeries. Buying a product involves trust, and for some people, greed can overcome integrity.
