The cheapest LispWorks hobby license is $500 USD in North America [0].
The cheapest Allegro license is $599 USD [1].
If you're already a highly productive professional, this is probably totally worth it. For everyone else, there's no way you're going to get newbies to pay even close to that much, while DrRacket and Thonny are both free-as-beer and free-as-in-freedom.

If I'm a solo developer, then sure, but right now I cannot think of a single non-trivial pro or hobby project that is run completely solo.
Asking contributors to shell out a sizable amount of money before they are able to submit PRs is a deal-breaker. It's just no going to happen no matter how productive those products make me, because next to none of my work and/or hobby code is done with the expectation that other people are not allowed to contribute.
Unfortunately the prices don't scale down, and there don't seem to be places that would offer installment payments...
Despite pretty sure being among better paid people in Poland, I'd need to save non trivial amount of my salary each month for a chance to buy necessary set of LW licenses for it to make sense :-(
