I dont disagree - if only for the fact that the density of cellular coverage is generally much higher than LoRaWAN GW’s in most places. Where there are co-located cellular & LoRaWAN GW’s the LoRaWAN reception area will often be much wider than that for cellular hence many telco/cellco’s have deployed as a complimentary technology 
In this specific case mentioned by Nick yes, but cannot be assumed for OP and often so. My comment relates to general cases, however, just as applicaple where the content is so precious - as an addition (re)assurance!
In such cases there is often both a datalogger (e.g. that can be checked on delivery to ensure no excursions/refreezing during transit) and a mechanism for best efforts live reporting and particularly alarming(*) - hence involvement of LoRaWAN. Indeed the fact these goods are so valuable - both in terms of actual COG’s and in terms of industry or societal value - often justifies the use of such multiple layered protections and monitoring.
(*) Best catch an excursion condition at the time and take immediate corrective action before material spoils, than review a datalog once delivered or days later when the damage already done and its scrap!
True other than for development/POC activities, though I know of many university and hospital engineering & support tech labs working on such projects, and they are extremely professional vs DIY/Hobbyists…and I am actually advocating professional vs hobbyist for precious cargo monitoring. There are obviously many players in the LoRaWAN ecosystem - many of whom are active on the Forum, and/or within the LoRa-Alliance, friends like Laird Tech, who have cold chain protection as a core use ( https://lora-alliance.org/sites/default/files/2019-09/get_smart_with_your_cold_chain_monitoring.pdf ) case for LoRa come to mind, as do smaller start-ups such as Ben, Steve, Ali & the team over at Koolzone here in the UK 
Absolutely agree - and that requires an open mind and not prejudging what can or cannot be done with the technology - after >9 years with LoRa then LoRaWAN I am pleased to say I still get a nice suprise every month and that is what helps keep me going with the tech despite odd sticky patches…I like a challenge
