With respect, your own comment reads as overly dismissive of the regulatory environment introduced by the GDPR. Systems (and companies) have for decades collected and stored personal data with little or no regard for the lifecycle of the data. Since the introduction of the Regulation, companies must now refrain from the collection of personal data if they cannot satisfy the rights of the data subject, including the right to erasure (which is obviously not an absolute right). If the technical solutions aren't performant or scalable enough for data controllers, then the result is that they cannot collect personal data. The idea that companies have in the past rejected solutions which protect the rights of data subjects because they were unwilling to accept the technical tradeoffs is exactly why strong regulation such as the GDPR is required. Frankly, your comment reads as contemptuous to the rights of the end-user. Thankfully, the EU offers protection to its residents from people with that attitude.
