Partially a cop-out. All "lifetime access to" responses, aren't realistic responses.

Depends on how you define 'lifetime'. Sadly I've seen many SaaS businesses dia and with htem the 'lifetime' access. Otoh my Plex Pass value is still holding strong. Finally if we're talking true lifetime, it can be averaged out to the median lifespan of subscribers, in my case $10k 'lifetime' it would work out to <$25/month
