Do you particularly need a gaming laptop for such infrequent use? I can't solve the blackouts / in for repair or upgrades issue, but I personally got a Steam Deck for this niche in my life and prior to that I used Moonlight to game stream from my home desktop when on vacation.
Not optimal for FPS games but for my use (MMO) more than sufficient. Just a couple potential options, obviously YMMV - Moonlight depends on your Internet connection on either side.
In getting mixed vibes. It feels like it's people with no relationship prospects (for whatever reason, and I can attest to this as one of them) who might tend toward the "2d girls > 3d girls" crowd getting a harsh reminder. That and the music.
