I guess, but they're a lot less optional and more useful.

I own my house, so I don't pay rent. My mortgage is below inflation and expected investment returns (it's even below risk free investments like CDs), so I actually make money by not paying it down.

Replacing gas/water/electricity/food with fixed cost items is more expensive. Electricity is the easiest, and going off-grid would cost $20-30k initially with a really good deal (assuming I DIY a lot of it; a lot of this is the battery backup), which if invested in the market would yield $1200-1600 the first year @ 6%. I only pay $50-100/month for electricity, so I'd pay more to generate it myself vs investing that money. The same goes for gas, water, and food, mostly because of the land requirement (need trees for heat, large plots for growing for, well access, etc). These items benefit from economies of scale, so it's absolutely worth paying based on use.

So it goes both ways. Some subscription-type things are cheaper long term, such as a Costco subscription or natural gas delivery, and some are likely more expensive, like paying for heated seats or many streaming subscriptions.
