by your own words, there's no safe way to get rid of nuclear waste besides storing it and hoping things will work out.

I think you're purposely misconstruing the meaning of safe. I think deep isolation is a proven method of safely storing radioactive material until it decays.

You are claiming it's unsafe, or "kicking the can down the road", but haven't explained your reasoning. Perhaps if you had any examples of how deep isolation has failed, or ways you think it will fail, it may strengthen your argument

Also, nuclear plants would take as long to build as other, safer methods.

Again, you are claiming things are safer, but haven't explained how? All forms of energy production have their positive and negative attributes, however safety isn't really a problem usually attributed to nuclear energy.

Time is generally an actual criticism of nuclear power, but a lot of length of time isn't really inherent in the actual construction of the power plant, which can be completed in as little as 3-5 years. It's usually the same problem as your first claim, the governments inability to deal with NIMBY campaigns and private interest.
