30+ Bitcoins? who's him? I think you're refer to Laszlo Hanyecz where he spend 10,000 Bitcoins for 2 pizza and he was not disappointed for doing it, so why you should care with it?
It's your choice if you want to pay with BTC or not, but I believe there's a time where you will convert your Bitcoin to cash because you will need that money in the future, you can't just hold it and not enjoy what you've accumulated so long.
All in all he actually spent over 30,000 bitcoins as he did a couple deals like his infamous 10,000 bitcoin for pizza trade that was the first ever bitcoin for goods transaction.
OP- I understand what you’re saying and where you’re coming from, but I think it’s also important to understand that bitcoin is first for foremost designed to be digital cash, meant to pay for things. I personally believe that it’s important that bitcoin be used as a means of currency as that gives it more value, legitimate utility.
So personally I feel no different spending it or traditional fiat.
