To fund a Lightning channel you have to pay fees on the Bitcoin network, which can get quite high. Up to 50 USD during times of high demand.

To send to someone who's offline the recipient either has to run their own always-on node, or use a custodial service.

Routing small payments (one of the goals of Lightning) is unreliable with a high chance of failure. See http://essay.utwente.nl/82015/1/Satcs_BA_EEMCS.pdf

The paper linked is called "Understanding the Lightning Network capability to route payments" which cannot be found in any reputable or peer-reviewed journal. How is that suppose to be a reliable study?
