It is a metric in case of many laws because of the huge amount of industry lobbying which prevents laws which benefit the common good and only benefit the short term goal of the industry, like this copyright law.
Copyright came about to support and foster creativity, it was meant as new form of property because creativity has no clear boundaries.
About the intentions of the GDPR, they were clearly to give people more control over their data and give business more restriction. The basic rule of the GDPR that companies should only store the data they really need at that time not more, not less. Overall this is what the GDPR does. My issues are more like, in some cases the burden for SME are too high and too weird for consumers. Like increasing the age limit from 13 to 16 or demanding complex privacy policies which no-one reads
The GDPR should have been the basic privacy policy for everyone, only if you do something different you have to transparent about it. Like transferring data to a third party.
