You have a point about the first part. Even myself I started off with no lightning wallet. Nostr in fact helped me get comfortable with the lightning network. Wallets are getting easier. I did have a hard time finding a simple lightning wallet. The only one I did find that was extremely simple is wallet of satoshi. 

The other part about Bitcoin skyrocketing. Bitcoin is designed to always go up. If everyone just hodls their Bitcoin it will slow down adoption.
It's up to the person to decide but I have always spent some Bitcoin from day one. I want to support the network and achieve faster adoption by buying things in stores. I see the price of Bitcoin at the time I spent it and whatever it will be worth in the future does not stop me from enjoying my Bitcoin. It's important for people to spend their Bitcoin. If it bothers people that much they can buy back what they spent.
