"hardly anyone could oppose regulating the wells involved."
This issue has been going on for a long time, even without fracking.
The issue always is access to natural gas pipelines. The natural gas comes up with oil production no matter what. Absent access to a pipeline, the well is "flared" and the natural gas is burned off.
This has been happening in Nigeria and other countries internationally for decades to due to gas rights disputes.
The question people should ask themselves is why oil & gas companies would voluntarily leave money on the table, and the answer is "they wouldn't." However, if you look at New York right now, and natural gas policy over the last 10 years, it has been actively hostile to building the pipelines that would prevent this resource from being wasted. The reality is the people "opposed" to fixing this problem are the people who force the oil production to happen without allowing the resource to be consumed.
