How is it possible that such a ridiculous law can be enforced country
wide in the United States?

It cant be enforced really, but people who spend time and money to come up with
new plants deserve to have the rights to those plants. Just like musicians
have the right to get payed for thier music. The laws concerning asexual
propagation are meant for growers, not homeowners. You can propagate anything
from the plants you already payed for as long as you arent selling them. Now,
if you are interested in rediculous laws, how can this country stop people from
growing and using for recreation plants that are found naturally growing in the
wild?
