True, but it will not be the only tool in the toolbox... So taking into account all the other software you've purchased, the costs will add up.

Just an anecdotal example, before JetBrains switched to their subscription model I was paying individual licenses for IDEA, PyCharm, and ReSharper. So if I had already spent over $300 p/a for IDE and tooling, another $70 will seem like an excess.
