Yep, but you'll miss out on joining when they offer $50 cash, or 6 tickets to the movies, or whatever else their bait marketing team comes up with. They know that, yes, they make most of their money from the big traders, but all of the Mum & Dad investors with a few hundred Telstra/CBA/AMP/NRMA etc shares still might sell them one day. Hence an offer like this to get you on their books and into their client database. If you have no need to trade or are unlikely to join up for any other reason, then go ahead.
