Internalise costs: storage, and bandwidth

Vitalik also had another nice backwards-compatible method in a previous thread where users are required to top up a contract’s TTL to 1 year every time they transact with it, and a contract only disappears if untouched for a year;

For ref:

• Improving the UX of rent with a sleeping+waking mechanism - general description of TTL mechanism;
• A simple and principled way to compute rent fees - #57 by vbuterin - 1-year TTL.

Thanks for mentioning this! It’ll take me a while to catch up with the previous body of work. (I see also that my concern’s been voiced here and there, albeit without a demo; and that the answer to “this will require a massive re-engineering effort!..” seems to be “yup”.)
