Option 1: break the law. Not advice, just acknowledging the possibility. I have little respect for legislation. What is the greater threat to you at the moment, though, lawlessness or law enforcement? Probably the latter.

Option 2: practice with what is legal and become proficient. Modern compound bows and crossbows are far more efficient and effective than their medieval or native equivalents. Axes can be tools or weapons, although when optimized for one purpose, they are less effective for the other. Never underestimate a basic machete. But I don't know what laws in your area apply to any of these.

The best plan for serious societal collapse is to have a community which exists in spite of government, not because of it. Political organizations may collapse, but churches and fraternal societies will be much more resilient. Know your neighbors and know who will be a real leader instead of a self-proclaimed ruler.
