To your first question, of course not, but that does not mean a parking lot attendant's job is pointless. The need for maintenance and security of a parking lot is inescapable. Clearly doing destructive things is destructive. Maintenance and security are productive activities, though. Yes, in an imaginary Kumbaya world where things don't deteriorate or get dirty and no one takes advantage of unattended, unsupervised property, you could do without the maintenance and the security. But that world will never exist, will it? So it's not pointless and it's not destructive. In fact, without the maintenance and security, the productive asset in this case would not be able to exist to provide the service to those who need it.
