Nothing that you said is wrong but it doesn't make the situation better.
1) As many people pointed out, this doesn't prevent OCR, it just prevents copying strings (e.g. with crawlers).
2) Majority of OCR doesn't deal with PDFs produced from a text source but either from a) jpg-scans of documents b) pdfs produced from those jpg-scans.
3) The first thing I tried, was OCR with my iPhone and it obviously worked. As someone else said, there're solutions that let you batch process many documents.
