Your argument is reasonable, however, you haven't explained why a purpose-built vector database is more scalable than any other DB with vector search support. Why is Elastic much slower than Pinecone? Is it because Pinecone is optimized in ways that Elastic cannot be? Is it because the Pinecone team has much better understanding on how to optimize vector search algorithms? or is it something else?
