I don't quite see your point

You don't understand LN.

If a single payment channel is enough for me to transact with everyone, why would each user be required to open a payment channel, and why it would require block space at that?

How exactly do you plan on paying me via LN when you have a channel with Alice, and I don't use LN? Roll Eyes

Do you even know/understand what opening a payment channel means?! It requires block space.

As I understand the technology behind LN, its main advantage consists specifically in lowering the load on the blockchain since transactions made via payment channels are off-chain transactions, right?

Payment channels which are opened and closed on the blockchain.

So why is there a need for block space at all if these transactions are never to show up on the blockchain?

Sigh. Nobody said anything about those transactions, but yes they don't show up on the blockchain.
