It's because the application:start/1 function doesn't expect
the argument to be wrapped inside a list.

You can write your own function that does expect the wrapper,
and simply unwraps it. For example:

-module(myapp).

-export([start/1]).


start([App]) ->
   application:start(App).


Then use: erl ... -s myapp start App
