Ah, transaction fees, the immune system against trolling, you say? Well, I suppose it's one way to look at it. It's like paying a toll to keep the trolls in check. But let's be honest, if someone wants to transfer the latest Lady Gaga video to all their friends via millions of transactions, we might need more than just transaction fees. Maybe some dancing robots or a few unicorn-powered servers could help with that one. In any case, kudos for being prepared and having other tricks up your sleeve!
