Sure, if I wanted the item. Most of the time, sellers who add a pick-up fee are valuing their time in a specific way, and do so knowing that many buyers don't value it at all (I have had some nasty messages in the past when I refused pick up, these people clearly expected me to just drop everything and be available to one person for X amount of time - I've even had people ask me to hand deliver items to them, for free, just because they live in a neighbouring suburb and they couldn't think of any reason why that might be completely out of my way and an imposition for me - I know a seller listing specifically with pick-up is a bit different, but I mention those things because you never know what the seller has had to deal with in the past - many sellers implement such charges, or terms, as a reaction to something that's already happened).
There is a lot of "I wouldn't do that as a seller, so for another seller to do it is unacceptable" around at times, too, when "what would I do?" is often no real basis for judgement, particularly when one only has a summary of facts (I am speaking in general, not to you or about this specific circumstance).
The following is also general, and obviously I don't know the item or seller in question so some, most or even all of these won't apply, but here are some of the reasons I can think of for a seller to apply a pick-up charge:
The seller doesn't want strangers coming to their home so will only arrange to meet in a public space, which is likely to involve travelling time / expense.
The seller has sold before and had experiences where it takes days of back and forth to organise a mutually agreeable pick-up time, and knows that people don't always show up when they say they will (if at all), and that many times people will try to re-negotiate the price once they're on the doorstep. If they've spent an hour or two organising arrangements for pick-up, and making time to be available for someone, $5 is cheap.
The item will require prep / packaging regardless of whether it's posted or not, and / or the buyer will require assistance to remove it (things like disassembly, or even special instruction for use / demonstration)
The item will require more than just a few minutes to inspect and remove, either because of the nature of the item, or because the seller is a chatterbox - perhaps the $5 is for tea / coffee & biscuits 
They are trying to eliminate certain types of buyers from their market
