Is there music without a tonic?
I.e., the structure of which is such that it makes no sense to talk about some stable home base note where we return. Or maybe music tonality changes so frequent that there is no point in talking about a tonic?

The simple answer is yes there is. The biggest example is atonal music where that is the direct goal to use pitches, but outside of the the concepts of things like tonality.
There is also music like drumlines which the music is purely rhythmic and pitches also don't matter.
It should be pointed out the the concept of tonic and tonality is a western music idea so other cultures do not all necessarily have similar concepts. Even the ones that do talking in terms of tonic and tonality will not make the most sense.
There are also some examples of music where you could talk about it terms of tonic and tonality, but it gets stretched really thin due to drifting from tonal concepts, with sprinklings of tonality to ground it. Impressionist composers like Debussy would be good examples of those where talking in terms of tonality is done, but it's one of many and just looking at it tonally won't give you the whole idea.
Yes.

are sort of equal, you might say the tonic becomes diffused or ambiguous.The terms above are often applied to and entire composition or even a composer's style. But you probably want to also consider that sometime just a section or passage may lack tonality. Liszt has a piece titled Bagatelle sans tonalité. I've never tried to analyze it, but I think there are passages that could be given a tonal center while other not. Other examples might include exotic scales like the whole tones or octatonic scales. Debussy's Syrinx is a nice example of his piano prelude Voiles.
I'm not including avant garde music, like musique concrète, or purely percussive music. I assume you meant music where clear pitches are used, but the tonic concept it not.
Also, keep in mind that while the specific word tonic (or its translation in other languages) is a European music theory term, the essential idea is not absent in other musical cultures. Indian and Japanese music, for example, have tonal systems with an idea of a "home" tone and named scale degrees. Tonic and dominant tonality is a European thing, but tonal structuring of pitches and a "home" tone are concepts found throughout the world.
In the broad sense of tonic as "home pitch" the concept is pretty universal and has existed for a long time, pretty much all of recorded music history. IMO it is notable the types of music that don't use a tonic, the types I gave in my initial list, are high art, intellectual forms. It takes some intellectual effort to have music that is tonally structured, not just chaos, and yet does not use a tonic.
Bimodality
A number of composers have experimented with multiple tonalities. This means that a piece of music can simultaneously be in two or more keys or musical modes.
Thus there is no single "tonic" that can be talked about although there may be a number.
Bimodality is the simultaneous use of two distinct pitch collections. It is more general than bitonality since the "scales" involved need not be traditional scales; if diatonic collections are involved, their pitch centers need not be the familiar major and minor-scale tonics. https://en.wikipedia.org/wiki/Bimodality
