Sure, Society in its majestic equality will allow rich and poor people alike to rent a new bio-heart with youthenating agents for 1 million dollars a month.

I would hate to have to rely on society to provide services like that. Chances are nobody except the top political brass ever gets their bio-heart.

Thankfully, society in its majestic equality allows all people to establish or invest into startups. Total addressable market at $1M/month is much smaller than at $1k/month, which is still much smaller than at $100/month.

Assuming the expenses are low enough to still give the company a healthy and IMHO fair 20-50% profit margin at $1k/month or $100/month, it'd be dumb to price it at $1M/month. There would be thousands if not millions of companies offering this service - and a race to the bottom of the pricing.

Kings died from infection and even criminals who practiced great evils are cured. You sound like you practice making scenarios where you're unhappy.
