You think that most people should rely on off chain solutions? Needing third parties in order to transact in Bitcoin defeats part of the purpose. We should be able to use the Bitcoin Blockchain directly, off chain solutions do not truly increase the throughput of the Bitcoin blockchain.
Nowhere did I say "most people should
rely on off chain solutions."
SC/LN do not require trusted third parties, and they do truly increase the throughput of the Bitcoin blockchain.
Sorry if that burns your butt.

They are third parties, and they do not increase the throughput of the Bitcoin blockchain directly, even larger deployment of SC/LN would still require a larger blocksize to support this in the long term.
I like the lighting network however I am skeptical of side chains due to them being to complex. Either way the blocksize still needs to be increased.
