Well we share the same age 🤣 Again I think we all want bitcoin to succeed as money. I prefer to be conservative and feel we already have a mechanism to defend against spam. That mechanism is called transaction fees. The folks spamming the chain will run out of bitcoin It is a free market though so you guys are free to run whatever implementation you want as long as it does not violate consensus and if it does you will be forked off so that is the risk you choosing to take.
