Not replacing the o-rings on an EGR valve will not cause an EGR cooler to fail. The most economical way to block the EGR cooler is to install a block-off plate in the EGR cooler flange. The most economical way to delete it is to fabricate your own cooler delete kit, (definitely not an easy job, however) There are also a few complete delete kits on the market, such as Adam's kit sold through Innovative. People clean the EGR valve to keep the carbon and soot out of it to eliminate the driveability and performance issues associated with a dirty valve.
