The recent surge in spam texts that show as having been sent by the recipient[0] has driven this point home for a lot of mobile phone users. For me, the fact that caller ID is fake was made evident when a spammer used my number as their origin ID for a wave of spam calls and texts, and I got ~100 voice mails and texts the next day kindly asking me to eat shit and die. Verizon support said that there was nothing they could do, that it was happening left and right, and that I was in no way legally or financially responsible for any of the messages purporting to be from me. This was in 2020, and the unreliability of long code origin ID numbers has come up frequently in my work as a security engineer for the past few years.
