Only if you are outside without Wifi you have to do another step, setting up a Wifi hotspot, but that is not hard. And in most situations I have been in both devices were in the same network anyways.
This assumes that the user has a level of technical knowledge that most people don’t have.
Edit: Ah maybe you thought setting up the server is an additional step. It is not. Share via HTTP is the server. It runs directly on your phone. The URL points directly to your device.
You scan a QR code to connect to someone's wifi.
All your traffic can now be captured. DNS requests will be logged. Some traffic might be redirected. When will the connection be closed? What if someone shows you a different QR code, and you're not that tech-savvy. For example a phishing webpage which asks for the user's password. Many many many people will still just enter their single-password-for-everything. What if the QR code is a deeplink to an app.. for example to a conversation on or whatever. Or maybe someone was previously logged in into some account.

The device then will do the "run a server with the file, create the QR Code for access, display it". Your mum has no need to learn how to run it, just how she doesn't need to know anything about how airdrop works to use it.
This will not work on many public and corporate networks. A common place where you’d want to share.

It’ll still suck compared to Airdrop. Apple has gone to a lot of trouble to make that work as well as it does. Trying to setup something relying on temporary hotspots will be sub par UX. (And a nonstarter for Apple devices - user apps can’t touch the WiFi settings).
Here is but one vendor doc. https://documentation.meraki.com/MR/Firewall_and_Traffic_Sha...
It is standard practice to enable this these days in public networks and it is so common that even consumer grade shit router now come with an option to enable.
For the server, on Android I use "Share via HTTP". On desktop running a lightweight HTTP server is easy too.
Edit:
Apparently that sounded complicated, here is how I can share a file from my phone to any other phone in the same Wifi.
- Click Share -> Share with HTTP.
- The app opens and shows a QR code.
- Other person scans the code. Their browser opens the file and they can do whatever they want with it.
If you have no Wifi:
- Open QR code for hotspot
- Other person scans QR code for hotspot, then for file.
If you still think it is too complicated, surely there is an opportunity create a simpler UI! From a technology perspective it does not have to be complicated.
