Two things come to mind:

1. "Home" download limits would likely become a limitation. Many ISP appear to have monthly data caps under a TB. https://broadbandnow.com/internet-providers-with-data-caps
2. Micro-transactions would not exist with out something like LN. Very few people would use stacker.news if they had to do a 200 sats on chain transaction fee to get off there 52 sats they received. 2.A. That would make @k00b very sad and we can not have that.
