Beaucoup is 'boku', not 'buku'. And having groups of letters be pronounced as a single sound is not the opposite of being phonetical, as long as the groups are used consistently (e.g. -eau- is always pronounced 'o', -ou- is always pronounced 'u', final consonants are never pronounced etc.) .
Granted, the sibling comment lists quite a few exceptions to these rules, but it is still quite a regular language.
The system of silent consonants is quite useful in keeping the language have somewhat regular declensions/conjugations. If they were not preserved, it would seem that French conjugations are mad, inventing consonants out of thin air. For example, coup/coupee, meaning to cut/ cut (up), are pronounced ku/kupe. This would make it seem like the participle is adding -pe to the infinitive (and it would add -te or -ze or many others), when in fact the participle is almost always adding -e, which forces the consonant in the root to be pronounced, since French really hates hiatuses.
If anything, French phonetics are the real problem, aggressively dropping consonants of the end of words, but loathing hiatuses, sometimes even between words in literary contexts (where sometimes a 't' or 'z' sound is added between a word ending in a vowel and the next word beginning with a vowel, 'la liaison').
