The assumption is that these freewheels will outlast the wheel and never need service.
There are 2 alternatives for removal, neither of which is practical. You can use a punch and drive off the cover, disassemble the freewheel and then use a pipe wrench, band wrench or vise to remove the inner body. That means you'll have to rebuild it, but then again, didn't you want to service it anyway?
Or you can use a large vise across the sprockets, applying enough pressure to ovalize the outer body and jam the freewheel. Then the wheel turns to the left to remove it. (wear protective glasses, sometimes the bodies shatter)
