You didn't understand the answer because you didn't actually ask a sensible question.
PPP is a "layer-2"
UDP is a "layer-4"

There are situations where one might encapsulate PPP packets into UDP
packets. This usually happens in back-hauls of ISP/DSL networks using L2TP.
But, that's not a typical situation for an end-user.
Myself and many others have built commercial BRAS using pppd, and there is
even support in the Linux kernel for efficient encap/decap of L2TP/PPP packets.
