I think the issue of "I want to play the game even after the servers are down" depends on the unlikely scenario that "the servers go down" within the medium-term future.
The platforms, unlike in prior generations, all have pretty much adopted the Steam service model going forward. That means the servers will almost certainly be up in two decades, just like Steam is still up currently. Unless the company goes out of business, you'll have your current games in 20 years, playeable on multiple platforms for the same copy.
I understand why people don't feel this will happen, given that past platforms have lost their server access, but the service model was different then than it is now. Switch purchases have followed people to Switch 2, and Switch/Switch 2 purchases are likely to follow to Switch 3. What happens then is less predictable, but the trend toward long-term, unified service models is clear.
