Your self launcher is limited to just launching you. *A winch can launch

For the electricity, but the cost of launches will be more as
maintenance and depreciation will have to be covered, as might the
cost of getting a power supply to all the places the winch might be
(I've seen 4 distinct locations where I fly, with two of them having a
number of variations - we try to get a straight into-wind launch) and
also wages for clubs which have paid winch drivers.
